Stephen Holler – Fordham Now https://now.fordham.edu The official news site for Fordham University.

The LHE reading at the top measures the movement of the sensor from east to west. The LHN reading on the bottom measures the movement of the sensor from the north to the south.When an earthquake shook the New York City area on April 5, Fordham’s William Spain Seismic Observatory captured it, confirming the 4.8 magnitude and recording further activity for the 40 minutes that followed.

A quick glimpse at a readout from the station’s instruments reveals a large spike around 10:23 a.m., followed by smaller spikes until 11 a.m., said Stephen Holler, Ph.D., an associate professor of physics at Fordham, who heads the station, located next to Freeman hall on the Rose Hill campus.

“But overall, this earthquake was a very short and very quick event compared to some of the others that we’ve seen where it seems like it kind of rings for a long time,” said Holler.

He said that although the quake, which struck in Lebanon, New Jersey, rattled residents from Philadelphia to Boston, it was not nearly as bad as other recent quakes.

“The 7.8 magnitude quake in Taiwan—that was 1,000 times more powerful than what we just felt, for perspective. They can get truly scary,” said Holler, whose expert commentary was featured by several media outlets throughout the day. But in the New York region, today’s quake was the largest felt since 2011.

As for aftershocks, Holler said residents need not be worried.

“There may be some aftershocks, which will be the ground resettling down after it slipped, but I don’t expect them to be any larger than what we just experienced,” he said.

The Fordham seismic station, which is operated by the Department of Physics, has been recording earthquakes around the world from the same small building on the Rose Hill campus since 1931. One of the few seismic stations in New York state, it now operates with digital technology.

It’s part of a vast network of monitoring stations that work together to determine data such as the strength and length of the quake, as well as the depth of it. Holler said it’s comparable to the way law enforcement uses data from multiple cell phone towers to pinpoint the location of a single cell phone.

The station has a state-of-the-art broadband seismometer and also houses a strong motion detector under a United States Geological Survey (USGS) program to assess earthquake risk remediation in large metropolitan centers. Data from the station is streamed to the USGS data repository in Boulder, Colorado.

The science of earthquakes has been studied at Fordham since 1910, when the first monitoring facility was constructed in the basement of Cunniffe House.

Rumblings from the offices of the University president apparently disturbed the sensitive instruments, so in 1923, the University constructed a new seismic observatory donated by William Spain and dedicated to the memory of his son William. It was moved several times before finding a permanent home next to Freeman Hall, where the physics department is located.

Caring for Our Common Home: Fordham Sustainability Update https://now.fordham.edu/university-news/caring-for-our-common-home-fordham-sustainability-update/ Tue, 19 Dec 2023 20:41:57 +0000 https://news.fordham.sitecare.pro/?p=180044 DID YOU KNOW? There are exactly 2,898 solar panels in three locations at the Rose Hill campus: 2,790 on the parking garage (pictured above in 2019), 24 on Campbell Hall, and 84 on Walsh Family Library. The University also buys electricity generated from a 9,000-panel array in Staten Island.

Last summer, in response to a call from Pope Francis to “take concrete actions in the care of our common home,” Fordham published the Laudato Si’ Action Plan.

The document set forth an ambitious seven-year plan for the University that touches on everything from facilities and curriculum to student involvement, all with the ultimate goal of combating climate change.

Just this month, Fordham received a $50 million grant from the Environmental Protection Agency that the University will use to team up with community partners to address the issue.

Below are a few of the sustainability-related efforts, developments, and accomplishments that took place in the final quarter of 2023. Look for more updates in 2024!

Facilities

Going Hybrid
On Oct. 23, three hybrid minivans, including a wheelchair-accessible minivan, joined the fleet of Fordham’s Ram Vans. They replace gas-powered minivans previously used for wheelchair-accessible requests, trips to the Calder Center, and charter trip services. The vans use less gas, produce less CO₂, and can run up to 560 miles on one tank of gas.

Dining

Micro Farms
This fall, Aramark installed vertical hydroponic units called Babylon Micro Farms at dining halls on the Lincoln Center and Rose Hill campuses. They grow fresh greens and herbs in a water-based solution (instead of soil, which requires frequent watering.) The greens are harvested for use in dining hall dishes and special student events.

Compared to traditional methods, each micro farm uses 96% less water, zero pesticides, 65% less fertilizer, and zero miles to transport. As a result, between January and June 2023, using them allowed Fordham to save 19,247 gallons of water, prevent 2.5 pounds of nitrogen from entering waterways, and reduce 32 pounds of food waste.

Academics

In the Classroom
Six undergraduate community-engaged learning classes offered in the Fall 2023 semester featured elements promoting sustainability: Anthropology of Food (Anthropology), Economics and Ecology of Food Systems (Economics), Thinking Visually (Visual Arts), Human Physiology (Biology), Consumer Behavior (Gabelli School of Business), and Leadership Integrated Project (Gabelli School of Business). At Fordham Law School, environmental law courses offered this semester included Environmental Law and Energy Law.

Fordham Law students wrote blog posts for the school’s Environmental Law Review on the Flint and Jackson water crises, NYC Local Law 97, the environmental damage caused by the fashion industry, and cell-cultivated meats.

Reading Laudato Si’
The Curran Center for American Catholic Studies held three seminars on Zoom this semester dedicated to reading Pope Francis’ encyclical Laudato Si’ and the 2023 follow-up, Laudate Deum. Visit the center’s website for more information on future seminars.

A Systems Approach
This semester, the Social Innovation Collaboratory and Career Center hosted a collaborative workshop on systems thinking, focused mainly on sustainability. The workshops, which were open to all undergraduate students, allowed them to explore the practice and application of systems thinking, which is rooted in a holistic approach to society’s more complex issues. The process is attractive to companies since it’s rooted in the idea of looking at complex problems with a new perspective. Contact Sadibou Sylla at the Collaborary for information on future workshops.

Students Take the Lead

Green Week: United Student Government sponsored Fordham College at Rose Hill’s Sustainability Week in November. It featured the Fordham Flea Pop-Up as well as a seminar on composting basics.

The Lincoln Center Environmental Club held a clean makeup tabling event on Nov. 30 to showcase the benefits of cruelty-free and clean makeup.

Community Engagement

As part of the Reimagine the Cross Bronx campaign, Fordham staff conducted weekend “walkshops” in the neighborhoods surrounding the highway. Funding came from a $25,000 grant from the New York City Department (DOT) that the Center for Community Engaged Learning received in October.

Fordham staff and students also held special Halloween and Thanksgiving-themed events at the Highbridge Farmers Market and community space, which was recently expanded thanks to an AARP grant.

Fordham and Bronx Schools Collaborating on Air Quality Project https://now.fordham.edu/science/fordham-and-bronx-schools-collaborating-on-air-quality-project/ Wed, 15 Dec 2021 14:28:30 +0000 https://news.fordham.sitecare.pro/?p=155780 Through a new initiative called Project FRESH Air, Fordham is working with local middle and high schoolers to combat climate change and generate new air quality data in their communities. 

“We want to set up a network of air quality sensors around the city and map out the air quality—particularly in the Bronx—and help students become scientifically literate activists in their communities,” said Stephen Holler, Ph.D., chair and associate professor of Fordham’s physics and engineering physics department, who is co-leading the project with Usha Sankar, Ph.D., an advanced lecturer in biological sciences. “Through our project, we can start a dialogue about climate change and say, ‘Let’s do something to fix it together.’”

Air pollution triggers many respiratory illnesses. One in 13 Americans have asthma, according to the Asthma and Allergy Foundation of America. Among the five New York City boroughs, the Bronx has the highest percentage of asthma diagnoses for children up to age 12, as well as the highest child asthma hospitalization rates. 

The goal of Project FRESH Air (Fordham Regional Environmental Sensor for Healthy Air) is to combat those statistics with education. 

Holler has started setting up a network of PurpleAir air quality sensors in middle and high schools in the Bronx and upper Manhattan, including Jonas Bronck Academy, All Hallows High School, and Cristo Rey New York High School. Each sensor—not just the project sensors in the city, but independent Purple Air sensors worldwide—records data 24/7. The data is viewable on an interactive map in real time.

The project garners interest because air quality is an issue people can relate to, Holler said. 

“I don’t think that many people in the Bronx are interested in the fact that it’s going to be one or two degrees warmer in a few decades. If you’re living paycheck to paycheck and worried about your kids, that’s not your high priority, right? So we’re tackling this issue by looking at it through an air quality perspective,” said Holler, who has previously worked with local students on climate change projects. “Air quality will degrade as the climate changes. We’ll have more pollution and particulate matter in the air from combustion sources, vehicles, and the urban environment, which irritate the lungs and aggravate asthma. But this is an immediate problem that we can address.” 

The FRESH Air team, which includes Fordham faculty, undergraduates, and middle and high school educators, is now working on ways to incorporate the sensors and their data into middle and high school curricula. Students will be able to build their own handheld sensors with special kits. They will also be tasked with plotting air quality data from their sensors and searching for trends. 

“They can plot the data in Microsoft Excel or Google Sheets and correlate it with factors like weather. Was the air quality better on this day or another? Was there a holiday? And they can start to understand the dynamics and patterns that are happening in their community,” Holler said.

This fall through a virtual webinar, the FRESH Air team introduced the project to students and families at Jonas Bronck Academy, located one block away from the Rose Hill campus. 

“The day after the informational session, our students were asking questions to all five of us teachers,” said Alexiander Soler, a seventh grade science teacher at JBA. “‘What is air quality? How does that relate to us? How does it connect to asthma?’”

Next spring, JBA will integrate Project FRESH Air into its sixth, seventh, and eighth grade curricula. The sixth graders will learn about air pollution and how it’s measured, the seventh graders will learn about health implications affected by air quality, and the eighth graders will learn how technology improves data collection, while using the sensors and their data, said Soler. Fordham undergraduates will also work with students on a weekly basis to help them analyze their data, said Holler. About 260 students at JBA will benefit from this curriculum, said Soler.

“These sensors are effectively going to be permanent installations,” Holler said. “Over the next two to three years, we are looking to have about 25 schools on this project.” 

The project originally emerged from the Higher Education Incubator and Think Tank led by Eva Badowska, Ph.D., dean of the faculty of arts and sciences and associate vice president for arts and sciences, and Anne Fernald, Ph.D., professor of English and special adviser to the provost, before the pandemic. It is being largely funded by James C. McGroddy, a former senior vice president and director of research at IBM who wants to promote STEM education, especially for minority and underserved populations. 

“The purpose of science is to gain an understanding of the natural world and its impact on our lives. This project will create a real scenario that our students can identify with, and hopefully increase their interest in science and becoming problem-solvers,” said Soler. “It will allow our students to see how science truly affects their lives.”

Remote, In Person, or Both, Fordham Professors Prioritize Academic Rigor and Connection https://now.fordham.edu/university-news/remote-in-person-or-both-fordham-professors-prioritize-academic-rigor-and-connection/ Wed, 16 Sep 2020 14:48:14 +0000 https://news.fordham.sitecare.pro/?p=140484 Perusall, a platform being used by Jacqueline Reich for her class Films of Moral Struggle, allows students to annotate scenes from movie movies, such as the romantic drama film CasablancaThis semester, Fordham welcomed back students for an unprecedented academic endeavor.

On Aug. 26., in response to the COVID-19 pandemic and the state restrictions on mass gatherings, fall classes at the University commenced under the auspices of a brand-new flexible hybrid learning model.

The model, which was laid out in May by Dennis Jacobs, Ph.D., Fordham’s provost and senior vice president for academic affairs, is designed to be both safe and academically rigorous. After being forced to pivot to remote learning in March, professors and instructors, aided by Fordham’s IT department, spent many hours this summer preparing to use this model for the fall.

Today, some classes are offered remotely, some are offered in-person—indoors and outdoors—with protective measures, and still others are a blend of both. Whatever the method, professors are engaging students with innovative lessons and challenging coursework.

Rethinking an Old Course for New Times

Barbara Mundy, Ph.D., a professor of art history, said the pandemic spurred her department to reimagine one of its hallmark courses, Introduction to Art History. The course, which covers the period from 1200 B.C. to the present day, is being taught both in-person and in remote settings to 327 students in what’s known as a “flipped” format.

Before classes are held, students are provided with pre-recorded lectures, reading material, and videos, such as Art of the Olmec, which Mundy created with the assistance of Digital and Visual Resources Curator Katherina Fostano and her staff. When students meet in person or via live video, they then discuss the material at length. The content was changed as well; it now also addresses the representation of Black people throughout history and showcases artists who tackle themes of racism.

“Because we were looking at a situation where we couldn’t just do business as usual, I proposed that we take this moment to really rethink our intro class, which we’ve been teaching for decades,” Mundy said, noting that the department has expanded in recent years to include experts in art from more diverse sections of the world.

Contemplating the Bard

Before the COVID crisis, Mary Bly, Ph.D., professor and chair of the Department of English, presented materials to students in her Shakespeare & Pop Culture class and encouraged them to generate their own ideas on them during live discussions. Now she breaks her students up into pairs, and later “pods,” of about six students on Zoom, to form a thoughtful argument about a particular work of art, video, film, or theater.

“An argument is not a description,” said Bly. “It has to have some evidence or context to make their argument, say, for example, ‘This film is a racist portrayal of the play for the following reasons,’ or, ‘The director of this film pits the values of pop culture against Shakespeare and the British canon.”

To propel the conversations, she created a series of video-taped lectures with Daniel Camou, FCLC ’20. In some cases, students are expected to respond with a video of their own.

Embracing New Technologies

For her class Medieval London, Maryanne Kowaleski, Ph.D., Joseph Fitzpatrick SJ Distinguished Professor of History and Medieval Studies, meets with her students both in-person and online. Zoom provides a platform for live instruction, and Panopto allows her to share the lecture afterward.

Paul Lynch, Ph.D., an associate professor of accounting and taxation at the Gabelli School of Businesses, is teaching Advanced Accounting to undergraduates and Accounting for Derivatives to graduate students this semester. Of the five classes, four are exclusively online, and one is exclusively in person. For his remote classes, he’s turned to Lightboard, which allows him to “write” on the screen. He jokingly refers to it as his Manhattan Project.

“I love being in the class with the students. I enjoy the interaction, and I thought that was missing,” he said. “This gives me the ability to let the students see me as if I was in class writing onto a transparent whiteboard.”

He said he hasn’t had to change much of the content. The only major difference now is that instead of passing out equations on printed paper, he emails students custom-made problems in PDF format, and then edits within that document after they’re sent back.

“I’ve always given them take-home exams, and always worked off Blackboard, so it’s just a natural extension of what I used to do in class,” he said.

In Jacqueline Reich’s class Films of Moral Struggle, students are using the platform Perusall to examine how films portray moral and ethical issues. They watch and analyze films like Scarface, a 1932 movie about a powerful Cuban drug lord, and The Cheat, which shows the early representation of Asians in American films, said Reich, a professor of communication and media studies.

Among other things, students can use Perusall to annotate scenes from movie clips, such as the classic film Casablanca, where they identified shots ranging from “establishing” and “reaction” to “shot/reverse shot.”

“It’s a really good exercise to do in class when you’re teaching film language or talking about editing or lighting, because students can pause and comment on a particular frame,” Reich said.

She meets with 11 students on Zoom on Thursdays and another eight in person at the Rose Hill campus on Mondays.

Sign announcing Fordham's new Main Stage theater season
Despite not being able to stage live performances, the Fordham Theatre program’s Main Stage season, “Into The Unknown,” is still proceeding online, as are the majority of its classes. Men on Boats, its first main stage production, will run Oct. 8 to 10.

In another virtual classroom, Peggy Andover, Ph.D., associate professor of psychology, is teaching undergraduates at Rose Hill how the laws of the environment shape behavior in an asynchronous class called Learning Laboratory. Andover said that platforms like Panopto, which transcribe her lessons, can make it easier for students to look for specific information.

“Let’s say you’re studying for an exam, and you see the word ‘contiguity’ in your notes, and you don’t remember what it means. You don’t have to watch the entire lecture again—you can search for ‘contiguity’ and see the slides and the portion of the lecture where we were talking about it,” Andover said.

Graduate students teaching in the psychology program are also using Pear Deck to make their virtual classrooms more engaging on Google Slides, she said.

“You have this PowerPoint that’s being watched or engaged in asynchronously, but [Pear Deck] allows you to put in interactive features,” including polls and student commentary, she said.

“Our grad students found it’s a way to really get that engagement that they would potentially be missing when we went to online learning.”

Learning from Classmates

Aaron Saiger, a professor at the Law School, made several adjustments to Property Law, a required class for all first-year law students. Instead of meeting in person twice a week for two hours, his class of 45 students meets on Zoom three times a week for 90 minutes, an acknowledgment that attention spans are harder to maintain on Zoom.

The content is the same, but the way he teaches it had to change. While he was able to record four classes’ worth of lectures to share asynchronously, that wasn’t an option for everything.

“I’m spending less time talking to students one-on-one while everyone else listens, which is the classic law school teaching mode; we call it the Socratic method,” he said. “Everyone else is supposed to imagine that they’re the person being called on.”

Saiger’s solution is having students share two-sentence answers to questions in the Zoom chat function to gauge what everyone’s thinking about a topic, having them do more group work, and leaning more on visual material.

“The difficulties are not insubstantial, but I think we are meeting the challenges and finding a few offsetting advantages that will make it a good semester for everyone.”

Getting Creative with Lab Work

Stephen Holler, Ph.D., associate professor of physics, holds most of his experimentation class in person, with a few students attending remotely.

The in-person group is working on a hands-on solar project that allows them to learn about the material, electric, programming, and optical components of physics.

Students who are attending the class remotely are doing related mathematical work as a part of their semester-long project.

“One student is studying interference coding in optics, so I have him looking at designs in a paper,” he said. “He’s learning all the underlying physics for what goes into a portion of these mirrors that are used in laser systems.”

a chemistry set
“You can’t have the kids in the lab, and at the same time, we can’t not have some kind of hands-on,” said chemistry professor Christopher Koenigsmann.
His students will be conducting experiments at home instead, using kits he’s sent them.

Christopher Koenigsmann, Ph.D., assistant professor of chemistry, is sending lab kits to the students in his general chemistry class so they can conduct experiments from home.

“We were between a rock and hard place—you can’t have the kids in the lab, and at the same time, we can’t not have some kind of hands-on,” he said.

The kits will allow students to participate in labs virtually through a Zoom webinar with their professor, as well as in breakout rooms with their lab teams.

“We adapted as many of our experiments as we could to just use simple household chemicals that are all completely safe,” he said.

Elizabeth Thrall, Ph.D., an assistant professor of physical and biophysical chemistry, likewise sent a kit to students that they can use to build a spectrometer. Students can build it out of Legos, using a DVD and a light source to create different wavelengths of light. They capture them using their computer’s webcam which processes the data. They will then design an experiment that everyone in the class will conduct.

“Designing an experiment so that you learn something, that answers the question you set out to answer, and gives a protocol that someone else can follow so they can get the same results that you got, is really at the heart of what it is to do scientific research,” she said.

Prompted by a Global Pandemic, Fordham Moves to Distance Learning https://now.fordham.edu/university-news/prompted-by-a-global-pandemic-fordham-moves-to-distance-learning/ Wed, 18 Mar 2020 13:59:52 +0000 https://news.fordham.sitecare.pro/?p=134086 On March 13, Mark Naison, professor of history and African & African American Studies, held his Research Seminar in African American and Urban Studies class on the Zoom platform. It is one of nearly 1,000 courses that have moved online.Cura personalis, or the idea of caring for the whole person, is a key part of a Fordham education. In the last three weeks, it has become more urgent than ever before.

So when Fordham ceased face-to-face instruction at 1 p.m. on Monday, March 9, due to the threat posed by the COVID-19 outbreak, faculty were faced with the challenge of providing quality instruction that was true to their mission of supporting students and continuing to foster their potential. On March 13, the decision to suspend face-to-face classes was extended through the end of the semester.

As they begin to deliver instruction remotely, faculty have turned to online tools such as Zoom, WebEx, Blackboard, and Google Hangouts to continue students’ education. And they have turned to each other for support, guidance, and tips.

Planning for the transition began in earnest during the last week of February, when Joseph M. McShane, S.J., president of Fordham, and Dennis Jacobs, Ph.D., provost and senior vice president for academic affairs, briefed members of the Faculty Senate at its monthly meeting on February 28. Administration officials had been monitoring the spread of the virus in China, and once a case had been reported in Washington state in January, they thought it might spread throughout the United States.

Jacobs said that at that time the University was already making plans to offer online instruction to students who’d been recalled from study abroad programs and who would need instruction while self-quarantining.

“That was the call to action, to say, ‘Let’s begin preparations,’” he said.

“No one would have chosen this as a normal transition path, but these are extraordinary times, and our options were limited,” he said.

“Everyone was committed to serving our students and allowing them to progress towards their academic degrees. It was not just an option to shut down the campus, we had to come up with a continuity plan.”

Technology and Pedagogy

Making the transition required overcoming challenges both technical and pedagogical. Steven D’Agustino, Ph.D., Fordham’s director of online learning, is helping faculty figure out how to best use that technology to deliver their coursework. He’s offered videos and documentation on the University’s Official Online Learning Page and his blog, Learning at a Distance.

D’Agustino said he was impressed at how seriously faculty have put students’ well-being and peace of mind first and foremost. Many are using this week, which happens to be spring break, to explain to their students how they plan to move forward with the rest of the semester and taking steps like telling them exactly what times of the day they’ll be checking their emails. Faculty are establishing virtual office hours when they’ll be available for in-person consultation, and giving serious thought to whether future classes should be held synchronously, when everyone meets together, or asynchronously, which enables students to access material on their own schedules.

D’Agustino encouraged faculty to evaluate their methods as they go, and to draw on the experiences of peers across the country who face the same situation.

“I would say reflective practice is really valuable. This about what you’re doing, and reflect upon it after you’ve done it, and try to include your students and your colleagues in those reflective spaces. Because I think there are a lot of good ideas and support out there, and we’re not alone.”

A Quick Turnaround

Eve Keller, Ph.D., professor of English and president of the Faculty Senate, said she was astonished at how quickly faculty, who teach nearly 2,000 courses a semester, were able to work together to make the transition.

“Faculty had 36 hours to convert their classes online. Some people have done this, and some people had never heard of Zoom, but from what I’ve seen, it’s been an unequivocally congenial, collegial effort to make it happen,” she said.

The transition has not been without occasional hiccups. Anne Fernald, Ph.D., a professor of English and special adviser to the provost for faculty development, emailed fellow arts and science faculty for thoughts on pedagogy on March 11, and after receiving 20 replies, she felt prepared.

Still, when she attempted to teach her first class on Thursday with WebX, she didn’t realize the program’s default volume setting for the program is mute. She ended up recording a podcast for it with the information she planned to share, and is confident she’ll be able to make it work next week, when spring break ends and classes resume.

“I felt like the University did everything it could in this emergency to support us. And I think that the decision to be closed on Tuesday and give people time to prepare was huge. I had colleagues all around the country who didn’t have anything like that. Fordham did it in a way that was as compassionate as it could be,” she said.

Striking the Right Balance

On March 12, Mark Conrad, an associate professor of law and ethics at the Gabelli School of Business, taught three courses—Legal Framework of Business, Sports Law, and Law and the Arts—using the Zoom platform, and was happy with how it came together.

“I’ve been pleasantly surprised at how easy and accessible it has been. I had a number of questions from students. I wasn’t just talking to a computer,” he said, noting the ease in which he was able to share power point slides with students.

We’re seeing future possibilities. It deals with something I’ve been thinking about which is, let’s say the professor is ill or has a sprained ankle. One could do classes like this, and it could actually minimize absences.”

Nicholas Tampio, Ph.D., a professor of political science, taught two classes on March 11 using WebX seminar after department chair Robert Hume, Ph.D., arranged practice sessions for the department. While they went off without a hitch, he said it was hard to read the mood of a room, as many nonverbal communication cues were lost in translation.

“When you teach online, you can’t see feet shifting, or if they have another browser open where they’re checking email. Their parents could be in the room, there could be a car going by. It’s not a controlled environment in which students are only there for the experience,” he said.

“I think I’m going to get better over time at being able to call on people, and I think I’m going to get better at organizing my slide show to make it more entertaining,” he said. But he acknowledged that face-to-face learning will always be preferable.

Edward Cahill, Ph.D., a professor of English, had never used Google Hangouts before and turned to it to teach Shakespeare’s sonnets and John Milton’s Paradise Lost. He found it to be similar to the normal classroom experience, although he said he plans to try different approaches to keep things interesting when the semester resumes, including splitting the class into both synchronous and asynchronous sessions.

Cahill’s new familiarity with online learning comes not only from his work as a professor, but also a student. His experience as a student in an entry-level Spanish class taught by Guillermo Severiche has given him hope that success is possible in the online realm, he said. Severiche, an instructor in the department of modern languages, moved their class to Zoom as well.

“We share documents, we used the e-textbooks. He managed the whole thing flawlessly. So that inspired me to think maybe I can do more.”

Cahill noted that he’s trying to be mindful of the challenges inherent in asking students to complete studies in the midst of a worldwide pandemic.

“There are so many balances to strike between rigor and flexibility, generosity and intensity. I don’t know that anyone has figured it out, and I guess as long as we can stay alert to all of those tensions, we’ll probably find our way through it,” he said.

Doing Lab Work Without the Lab

In some fields, resuming instruction is trickier than just establishing online connections. Stefanie Bubnis, interim managing director of the Fordham Theatre Program, said that while mainstage productions have halted, faculty have bolstered instruction on Google Hangouts and Zoom with old fashioned phone calls and FaceTime.

Professors such as Ann Hamilton, an adjunct professor of theater, are learning on the fly as well. For her first online Acting for the Camera class, she asked students to upload the scenes they recorded of themselves to Hightail and Google Drive. She watched the videos during the designated class time and wrote feedback in a group email to the 17 students in the class. Ultimately it proved to be too time-consuming.

“For my next class I intend to use Zoom, so we are all conferencing together, but they will have sent me the recorded auditions first, so I can have them up on my desktop and we can all watch them together at the same time and actively participate in the feedback. I think the students felt as if they learned a lot today, so that’s a win, given the circumstances,” she said.

Stephen Holler, Ph.D., an associate professor of physics, was able to move the lecture for his General Physics 2 class exclusively to Blackboard, but that wasn’t an option for Experimental Techniques for Physics, a course where teams of students had been working on a single project all semester.

“Some of the work, they’re in the machine shop, they’re doing 3D printing, they’re doing electronics,” he said, noting that this work will have to be completed in a different way than planned.

“Since they’ve done half the project, and they’ve already written up progress reports, I’ll have them turn those progress reports into a paper. Normally I’d also have them do a presentation on a research project they’re interested in; instead I’ll have them write a short paper on that and we’ll do Zoom presentations.

A Big Shift for Information Technology

For Fordham IT, the switch required an unusually speedy response.

Alan Cafferkey, director of faculty technology services, noted that his team—which includes experienced technicians, a fine arts and digital humanities professional, instructional designers, a former math teacher, a librarian, adjunct professors, a media and accessibility expert, and an Ed.D. candidate—normally prefers to work with six months lead time to develop an online course.

“This, however, was everyone already two months into the semester with only a couple of weeks of realizing that something might happen, prepping, and then a sudden shift, with hundreds of people making the change,” he said.

He was especially proud that his team was so on top of responding to the multitude of individual faculty requests. In addition, in collaboration with the provost’s office, they created a Course Continuity site before the University shifted to online learning—as preparation for what might happen.

When the switch was made, IT as a whole simultaneously shifted its entire operation to function remotely—including the IT Customer Care help desk—while helping other offices do the same.

IT also rolled out an entirely new enterprise-wide system in Zoom, reinforced numerous systems, and conducted a multitude of workshops on topics such as teaching synchronously and asynchronously, setting up remote offices, and best practices for many popular web tools. Additional workshops will continue through the spring and can be found on the department’s blog.

Going forward, Cafferkey said the department will continue to field faculty questions and requests, work closely with vendors such as Blackboard, and support other University initiatives as needed. He credited the efforts of colleagues across IT, the provost’s office, the IT departments in the Gabelli School of Business and Fordham Law, the online learning teams at the Graduate School of Social Service and the Graduate School of Education, and the staff at Fordham’s library.

“I’ve been really touched at how kind most of the faculty have been about the support provided. I’ve gotten so many thoughtful notes and comments, it’s been really heart-warming. It’s helped that there are so many offices working collaboratively,” he said.

Looking at the Big Picture

Lisa Holsberg, a Ph.D. candidate in theology, found herself transitioning Great Christian Hymns, which she is teaching for the School of Continuing and Professional Studies (PCS), entirely online. But she was in some ways already prepared to do so, as she is also currently teaching an online course, Christian Mystical Texts, for PCS. She was already accustomed to using Blackboard extensively, as well as Screencast-O-Matic and Voicethread, which lets students listen to each other talk, in their own words, about a specific problem. But ultimately, technology is just one little piece of the story, she said.

“It’s really, what is your commitment to students and to learning and going forward in the midst of change? How do you rethink what it means to teach, what it means to learn in conditions you’re not used to? You have to really dig deep into what your fundamental commitments are to your teaching, your students, to yourself, to your topic, and then just use whatever tools you have in order to meet those goals,” she said.

The Path Forward

Going forward, D’Agustino said he thinks faculty will settle into a hybrid approach for the rest of the semester, making tweaks as they get feedback from students.

“They may say, ‘We’re going to do a synchronous session, so here are the slides in advance, here is the reading material, here’s the study guide, there are some questions you should be able to answer during the session,’” he said.

“So even if a student can’t attend or log in, they still have the notes, the readings, the study guides, and they can say, ‘Professor I couldn’t log in; its 4 a.m. for me. But here are the answers to those questions. And the faculty member can, if it’s part of their protocol, share those answers with the class so that student is part of it.”

Jacobs said that he’s hopeful that faculty will rise to the challenge in what is an extraordinary time of upheaval. He noted that online instruction will always have a place in graduate level and professional-oriented instruction, especially for students who are working or have family obligations. As such, the University will continue to evaluate it on a case-by-case basis. But face-to-face teaching and learning is at the heart of Fordham’s mission, he said.

“Jesuit education is really one of formation in context of community. We treasure that at Fordham, and we always will. It’s the reason why during the academic year, we have not, by intention, moved our undergraduate academic offerings into an online format. We’ve offered them face-to-face, and will return to that when it safe to do, when the virus has passed,” he said.

Local High School Students Monitor Carbon Dioxide Levels at Fordham https://now.fordham.edu/science/local-high-school-students-monitor-carbon-dioxide-levels-at-fordham/ Thu, 22 Aug 2019 14:39:55 +0000 https://news.fordham.sitecare.pro/?p=122994 Three people pose for a picture in a laboratory. A person holds a science instrument that looks like a bottle. Two high school students work on scientific devices. A computer and a scientific device that looks like a box. Deep in the basement of Freeman Hall, two local high school students and a Fordham professor have been monitoring carbon dioxide levels on campus. 

Over the past six weeks, the team of threeStephen Holler, Ph.D., associate professor of physics; Alan Vara, a rising senior from the Bronx; and Bryant Ramos, a rising senior from Brooklyn—have been collaborating on climate change research through the Fordham Science and Technology Entry Program (STEP), designed to help underrepresented students in junior and high school prepare for STEM-related careers. Inside Holler’s lab, they controlled a carbon dioxide sensor, calculated CO2 concentrations, and dissected their data. At the annual Calder Summer Undergraduate Research Symposium on Aug. 8, they presented their research results alongside six other STEP students, who developed projects related to biology, psychology, and chemistry.  

But what seems to have had the largest impact on them, said Vara and Ramos, was learning about the increasingly devastating effects of climate change. Recent historically high carbon dioxide measurements at Hawaii’s Mauna Loa Observatory have made them consider the impact of CO2 in their own homes in New York City. 

“You can see that it’s not just thereit’s our neighborhoods as well,” Ramos said. 

“It’s a lot more personal. You realize that it’s not [just]in some far off island,” Vara chimed in. “It’s right here, where you live and enjoy your life.” 

Dissecting the Science 

In mid-July, the two high school students began visiting the Rose Hill campus several times a week. 

“Every day they’d come in, and we’d sit down, get the software up and running, start building the box,” Holler said, referring to the box that held their carbon dioxide sensor. “[Then] we’d do some machining and programming.” 

The trio’s main tool was a non-dispersive infrared (NDIR) sensor: a special device that converts light rays into numbers. The sensor sucks air into a tube and shines infrared light through the gas. The infrared light comes from a lamp at one end of the tube and shines through to detectors at the other end. A pump sucks in the air from the outside into the tube.

At the other end are two detectors that measure the intensity of the light coming through. What Holler and his two mentees were concentrating on, said the professor, was the way the light interacted with carbon dioxide molecules. 

“[CO2] is one carbon and two oxygens. They’re bound to each other. You can think of them as being little masses on springs. They vibrate at certain frequencies. And when your light source corresponds to that frequency that they like to vibrate at, you’ll get light absorption,” Holler said.  

In other words, the carbon dioxide absorbs some of that light, thus removing the light from inside the tube. Meanwhile, one detector at the back end measures how much light was absorbed. The other detector measures the amount of remaining light.

“Based on those relative intensities, I can say something about how much CO2 is in the tube,” Holler explained. 

The Earth’s rising carbon dioxide levels are primarily the result of fossil fuel burning. This leads to rising sea levels and other phenomena that can negatively affect communities and creatures around the world, as Holler’s high school students have observed this summer. Although the air at the Rose Hill campus is safe, they wanted to take a look at how the carbon dioxide levels fluctuate, particularly during morning and evening rush hours, said Holler. 

The team ran the NDIR sensor several times throughout the summer: twice in the lab overnight, and a few times in the lab for an hour and a half. Sometimes they threaded a tube from the box through a lab window outside; other times they measured CO2 levels in the lab itself. Then they graphed the CO2 concentrations and analyzed their results. 

They noticed that during the morning and evening rush hours, there was a slight increase in carbon dioxide. When the lab’s air-conditioning unit shut down at night, there was an increase in carbon dioxide levels due to the warmer temperatures, as opposed to during the day with cooler temperatures. Their indoor vs. outdoor data were relatively similar. 

Overall, the results of their preliminary experiment have prepared them for final data collection tests in the future, Holler said.

“[This shows] that we can have an instrument that monitors CO2 in here,” he said. “We know we have some improvements to make in the way we collect the data.” 

But ultimately, Holler wants to create a local network of CO2 sensors that could spark more dialogue about climate change. Instead of having people hear about data from distant places like Hawaii, he wants them to see what’s happening right in their neighborhoods—and realize that this issue does impact them, Holler said. 

“What I want to do is really have a tool for communicatingthat we can engage non-scientists, we can engage the public on these issues that we’re dealing with right now,” he said. 

Bringing Climate Change Closer to Home 

Ramos said he knows that climate is real. But it was surreal to learn about the issue up close—to learn how a local sensor could capture carbon dioxide data in his own city. 

“We were talking about the environment and stuff at school,” said Ramos, who attends the Manhattan Center for Science and Mathematics in East Harlem. “I can bring this to school and share it [with people].” 

Vara, a rising senior at the High School for Mathematics, Science, and Engineering at City College echoed the same sentiment. 

“We got the device up and running, but then there was also a why to it. We had to understand why we were building it, what the point of it was, what we were trying to convey in graphing data,” said Vara. “We [also]saw videos about Hurricane Sandy and how it affected Staten Island and how just a couple of centimeters of water, like sea-level elevation, has a disastrous effect for the people on the coast. Getting to see that climate change isn’t as distant as a lot of people would thinkit’s not a 100 years into the future; it’s something that’s affecting people right now—that was definitely eye-opening.”

From the Study of Classics to the Frontiers of Aerospace https://now.fordham.edu/fordham-magazine/astronauts-will-answer-nasa-interns-question-live-from-orbit/ Thu, 26 Jul 2018 19:35:27 +0000 https://news.fordham.sitecare.pro/?p=100379 Bernadette Haig posed a question to an astronaut aboard the International Space Station while serving as a NASA intern. Photo courtesy of NASA As part of a summer internship at NASA, Bernadette Haig, FCRH ’18, had the opportunity to pose a prerecorded question to an astronaut about the value of human spaceflight.

On July 30, the answer came from space: a call for human unity during a time of bitter conflicts, articulated by someone who is—quite literally—above it all.

“We watch the news up here every night, and we’re aware of what is going on in the world,” said Ricky Arnold, a NASA flight engineer aboard the International Space Station, speaking via live webcast. He cited the crew’s cooperative efforts as an example of what can happen when people from diverse nations work together.

Haig and her fellow interns watched from NASA’s Glenn Research Center in Cleveland.

“It was really exciting,” said Haig, who is getting ready for the fall quarter at Stanford, where she will pursue a master’s degree in aeronautics and astronautics.

The experience, part of a NASA educational program, fueled her enthusiasm for becoming an aerospace engineer and, hopefully, an astronaut herself one day. It also provided a thrilling coda to an undergraduate career that was heavy on science and grant-funded scientific research but also on classic humanistic aspects of Jesuit education.

Science Studies Inflected with Jesuit Values

Haig graduated summa cum laude from Fordham in May with a double major: engineering physics, with a concentration in mechanical engineering, and classical civilization. At NASA in Cleveland, she spent the summer in the ARETEP (Aeronautics Research and Engineering Team) program, studying the movement of urban air masses with an eye toward safety standards for new aerial vehicles that could one day be zipping around city skies.

Aviation is a longtime interest. In high school, she volunteered at an aviation museum near her Long Island home and enjoyed working with the museum’s elderly docents—an experience that led her to volunteer at Fordham as an aide to a former missionary—Richard Hoar, S.J.—living in the Murray-Weigel Hall retirement residence on the Rose Hill campus. “He actually has a master’s degree in physics, so it was a great fit,” Haig said.

A student in the honors program, she loved the program’s classics-related courses and kept signing up for more of them—Roman art, Latin, Greek. “Before I knew it, I had a major,” she said. For her senior thesis, she melded her two majors by examining how the Romans, known as great engineers, might have managed to fill the Colosseum with water for mock naval battles, as some have suggested they did.

There’s little evidence this happened. However, “the drains underneath the Colosseum are a lot larger than they would need to be just for rain water and waste water,” Haig said.

She also pursued varied scientific research projects. During the summer between sophomore and junior years, a Fordham Undergraduate Research Grant made it possible for her to work with physics professor Stephen Holler, Ph.D., on developing a new optical-fiber probe for use in analyzing tumors. For her second undergraduate research project, she worked at the Fermi National Accelerator Laboratory outside Chicago between junior and senior year and diagnosed a malfunction in the accelerator’s monitoring components.

She traveled to present her research at academic conclaves on the West Coast, thanks to travel grants provided by the University, and recently was awarded the Fordham College Alumni Association’s Undergraduate Research Symposium grant.

Haig suspects that her research helped her attain the NASA internship, a long-sought prize.

“I’ve been applying for the NASA program for a while, for at least a couple of summers, and I guess this summer I finally had enough research experience,” she said.

She found the internship to be a cornucopia for the scientifically curious. In addition to getting intensive introductions to aerodynamics and computational fluid dynamics, Haig has found scientists and engineers readily responsive to her email queries.

“I’ve found everybody to be so helpful and so willing to talk about their projects,” she said. “There are people working on missions that are going to Mars, stuff that’s going into deep space eventually. People say, ‘Yeah, come on over.’ I’ve been able to make so many connections.”

Aiming a Question at the Heavens

When she was chosen to record a question for the space station’s astronauts, she moved away from the technical and leaned toward the liberal arts, asking a question with a philosophical bent: “In today’s world, what is the most compelling reason to engage in human spaceflight?”

In his answer, Ricky Arnold, the NASA flight engineer, cited the scientific research conducted in space, as well as the crew’s perspective—“a higher plane of agreement”—on all the strife occurring far below.

“We have two Russians, three Americans, and a German right now,” he said, bobbing up and down in the zero gravity and casually moving his hands away from the microphone floating in front of him. “We have found something we all believe in, and the operations both here and on the ground are seamless because we all believe in the same thing. …

“There’s a really powerful message to all humans about what we as a species … are capable of when we put aside differences and focus on higher objectives as a species.”

In Uganda, a Fish Farm Takes Shape with Students’ Help https://now.fordham.edu/university-news/in-uganda-a-fish-farm-takes-shape-with-students-help/ Wed, 27 Apr 2016 14:19:33 +0000 http://news.fordham.sitecare.pro/?p=45899 Fordham Engineers Without Borders chapter members (left to right) John Murray, Delaney Coveno, Grace Bolan, and Michael Yu, are shown with their Ugandan partners and Timothy Weiss, a professional engineer serving as mentor.In a rural part of Eastern Uganda, where both technology and technical expertise are sparse, a community is fashioning a new economic resource out of the earth underfoot—thanks to an international collaboration involving Fordham students and alumni supporters.

The resource is an artificial pond for raising fish, and it’s the inaugural project of Fordham’s chapter of Engineers Without Borders (EWB), founded three years ago. A team of students returned last month from the project site, where locals were abuzz with the possibilities for a better life that the fish farm represented.

“Some of the community members were [saying], ‘We’re just excited,’” said chapter co-president and Fordham College at Rose Hill senior Grace Bolan. “It really comes down to opportunity. Hopefully, it leads to economic development in the region.”

She and three other Fordham students—engineering physics majors all—went to Uganda from March 17 to March 28. Accompanied by a professional engineer who’s a chapter mentor, they oversaw the implementation of designs for the pond that they’d drawn up in the past year.

Designing the pond was just one facet of the project. Students also consulted with a student team from the Gabelli School of Business about funding it; presented the project to potential donors and to the national organization of Engineers Without Borders; and coordinated via telephone and e-mail with those in Uganda who would be doing the digging and building.

Along the way, they’ve learned a lot about applying their academic lessons outside the classroom, said physics professor Stephen Holler, PhD, a mentor for the Fordham EWB chapter.

“They’ve done a phenomenal amount of work in a very short time,” he said.

Fish Farming for Economic Development

The project originated in efforts by a Ugandan nongovernmental organization, the Serere Local Fish Farming Initiative, to promote fish farming for economic development in impoverished areas of eastern Uganda. The group submitted its proposed projects to Engineers Without Borders so that EWB chapters could apply to take them on.

The Fordham chapter picked up the project because it seemed relatively feasible—compared with, say, building a bridge or a dam—and because the community’s description of its needs and goals was appealing, members said.

A team of five students visited the region in the winter of 2014 to assess a few dozen fish farming sites and choose one that seemed the most viable. For the first project, they settled on Omorio Village, where a group of 20 families wanted to build a pond that would generate income to provide for their widows and orphans. The chapter also agreed to see four more pond projects through to completion in the years ahead.

The first trip and a portion of the return trip were funded by John Reddy, FCRH ’76, and his wife, Christa Reddy, in consultation with their daughter, Kathryn Reddy, a 2014 Fordham graduate who studied physics.

In addition to helping the Ugandan families, the Reddys saw a chance to expand opportunities in the engineering physics program and advance the Fordham mission of educating men and women for others, John Reddy said.

“What it came down to was, we believed that this was a great opportunity for the University and for the families that would be benefited by this,” he said.

The return trip was funded by multiple alumni donors–including the Reddys–in response to a challenge gift from George McCartney, FCRH ’68, and his wife, Mary Jane McCartney, TMC ’69, who learned about the project at a meeting of the Fordham University Science Council, an alumni group.

“They hit a home run with us at that meeting, because they described the project that they did in Uganda and we were fired up to help them make it a reality,” Mary Jane McCartney said.

Their presentation to the Engineers Without Borders national organization—which needed to approve the project—was similarly impressive, said Holler, who said he listened to the presentation via telephone. “They had answers for practically everything that was asked of them,” he said.

The donors’ money paid for tools and for materials like piping, bricks, and stone. It also paid for laborers’ wages and food, and for hiring someone to drive, translate, and provide security. Grants obtained through EWB paid for the students’ flights and for materials used in digging and excavating the pond.

A Cross-Cultural Collaboration

The workers in Uganda started excavating the pond in January, said Fordham College at Rose Hill senior John Murray, the project lead who spearheaded the design work with input from other chapter members and the chapter’s professional mentors.

The pond will serve as a model for others in the district who want to build one. The community members had experience with this kind of project; the Fordham team showed them some enhancements, like techniques for fully draining the pond between harvest cycles, Murray said. The pond is stocked with tilapia because they’re relatively easy to take care of, compared to catfish, which would be the other option, he said.

The students found it was enriching to interact with the Ugandans and learn about their culture and way of living. They said the Ugandans marveled at various aspects of American life, like the sunscreen the students were donning—“‘We thought you were putting it on for energy,’” said one of them, according to Bolan.

Said Murray: “It’s just fascinating to come face-to-face with a completely different culture with different ideas of what it means to just live day to day.”

Bolan said she was impressed with how readily the Fordham community rallied to make the trip happen—from the administrators who went out of their way to help to the donors who funded the trip.

“We’re so thankful to our donors,” Bolan said. “This experience is absolutely the most important thing I’ve done at Fordham.”

The Physics of Climate Change https://now.fordham.edu/science/the-physics-of-climate-change/ Mon, 28 Apr 2014 16:33:07 +0000 http://news.fordham.sitecare.pro/?p=28811

Renowned climate scientist Michael E. Mann has been on the front lines of the climate change debate for years. He was part of a team who shared the 2007 the Nobel Peace prize for its work on what is commonly known as the “hockey stick” curve graph that shows how the temperature of the Earth has risen over the past 1,000 years with the increase of industrialization and use of fossil fuels.

But he is also a target of climate change deniers, having had his emails hacked by deniers and given to politicians in an attempt to discredit him and his research.

Michael E. Mann

Mann, the director of the Earth System Science Center at Pennsylvania State University, has said that mankind is “wasting all this time” on the debate about whether climate change is real, rather than working to curb it.

Mann will speak at Fordham’s Rose Hill campus onWednesday, April 30 at 2:30 p.m. at Freeman Hall 103, along with physics professor Stephen Holler, Ph.D., on the basic underlying science of climate and climate change, including physically based models of the Earth’s climate. He will speak about an “Energy Balance Model” of the Earth’s radiative balance, which can be used to assess the historical changes in global temperature.

Mann is the author of two books: Dire Predictions: Understanding Global Warmingin 2008 and The Hockey Stick and the Climate Wars: Dispatches from the Front Lines, published in early 2012. He is also a co-founder and contributor to the climatology blog RealClimate.

Influential Whispering https://now.fordham.edu/inside-fordham/influential-whispering/ Wed, 29 May 2013 16:53:33 +0000 http://news.fordham.sitecare.pro/?p=6224 Physicist Stephen Holler brings startup know-how to his Fordham lab, where he researches sensor technology. Photo by Tom Stoelker

For Stephen Holler, Ph.D., finding the utility of physics beyond the classroom is a cornerstone of his teaching technique and, indeed, his entire career.

The assistant professor of physics wants students to understand how physics works in the real world and to be able to communicate those complex ideas to anyone. 

“There’s more to it than going into a lab, turning a knob, and getting some data,” he said. “You have to be able to convey that experiment in a way that’s nontechnical.”

Besides teaching physics to pre-med students, Holler also teaches an advanced course in engineering physics that can be relevant in fields such as medicine or patent law. Regardless, communication remains key, he said.

Before coming to Fordham, Holler was well practiced in communicating with a wide variety of audiences. In graduate school he worked with the U.S. Army on biological aerosol detection. He later went on to work as a staff scientist at Sandia National Laboratories before joining a startup, NovaWave Technologies. NovaWave specialized in laser-based sensors that detect chemical and biological agents and eventually specialized in greenhouse gas monitoring. In 2010, Holler and his partners sold the company, and a year later he joined Fordham’s faculty.

It is that sensor technology expertise he brings to Fordham as he and his students build a lab that expands on groundbreaking work he completed last year with researchers from the Polytechnic Institute of New York University (NYU Poly) and the City University of New York (CUNY). That research detected the smallest known aqueous-borne RNA virus by using a device called a whispering gallery mode biosensor.

To explain by way of an anecdote, Holler said the concept of a whispering gallery is familiar to anyone who has ever been to the Oyster Bar at Grand Central Terminal. At a precise spot outside of the restaurant, if one whispers down toward the terrazzo floor, the whisper ricochets up onto the arched ceiling and into the ear of the listener standing about 20 feet away. To the listener, it sounds as though the whisperer were standing right beside him or her.

The whispering gallery biosensor operates in much the same way, Holler said. But instead of sound waves, light of different colors are “listened” to and the “speaker” is a laser. It’s a tunable laser, so the frequency (i.e., color) of the light can be controlled.

The system employs two fiber optics to harness and measure the light. One fiber is formed into a very small glass ball that is about a hundred microns in diameter, about the same as a strand of hair. This ball becomes the biosensor, aka the whispering gallery. Another smaller fiber measuring about five microns, or one-twentieth of a strand of hair, runs very close to the sphere but doesn’t touch it. It acts as a light guide. As a laser shoots through one end of the fiber, a sensor measures the amount of light that comes out at the other end.

And, as the laser is tunable, the frequency can be adjusted so as to allow just enough light to fall off into the biosensor, where its ricochet movements throughout the sphere can be measured.

When the sphere is coated with a virus or antibody, it creates a further change in the measurement. The process suggests another anecdote.

“Think of it as, if you ring a bell and then you add chewing gum to the bell, it’s going to change the resonance of that bell,” said Holler. “In this case the virus that you put onto the sphere is the chewing gum and the sphere is the bell.”

Last summer, Holler and the NYU Poly/CUNY team added gold nanoparticles to the sphere to create even smaller “hot spots.” It further increased the sphere’s sensitivity and enabled them to measure a single sample of the world’s smallest known RNA virus. The breakthrough was published in the July 30 issue of Applied Physics Letters.

Holler expects further breakthroughs, including a method of detecting protein that appears concurrent with certain cancers. Because of the sphere’s hypersensitivity, his hope is that it will be able to detect cancers earlier than current methods can.

Holler said that Fordham’s own whispering gallery biosensor should be completed later this summer, after which he plans to team up with Patricio Meneses, Ph.D., associate professor of biology, who has spent the last decade working on the human papillomavirus, or HPV.

“I have been working in this area for 10 years, so in about five years it would be nice to see the research commercialized, and of some benefit to those health professionals doing medical diagnostics,” said Holler.

That research detected the smallest known aqueous-borne RNA virus by using a device called a whispering gallery mode biosensor.

To explain by way of an anecdote, Holler said the concept of a whispering gallery is familiar to anyone who has ever been to the Oyster Bar at Grand Central Terminal. At a precise spot outside of the restaurant, if one whispers down toward the terrazzo floor, the whisper ricochets up onto the arched ceiling and into the ear of the listener standing about 20 feet away. To the listener, it sounds as though the whisperer were standing right beside him or her.

The whispering gallery biosensor operates in much the same way, Holler said. But instead of sound waves, light of different colors are “listened” to and the “speaker” is a laser. It’s a tunable laser, so the frequency (i.e., color) of the light can be controlled.

The system employs two fiber optics to harness and measure the light. One fiber is formed into a very small glass ball that is about a hundred microns in diameter, about the same as a strand of hair. This ball becomes the biosensor, aka the whispering gallery. Another smaller fiber measuring about five microns, or one-twentieth of a strand of hair, runs very close to the sphere but doesn’t touch it. It acts as a light guide. As a laser shoots through one end of the fiber, a sensor measures the amount of light that comes out at the other end.

And, as the laser is tunable, the frequency can be adjusted so as to allow just enough light to fall off into the biosensor, where its ricochet movements throughout the sphere can be measured.

When the sphere is coated with a virus or antibody, it creates a further change in the measurement. The process suggests another anecdote.

“Think of it as, if you ring a bell and then you add chewing gum to the bell, it’s going to change the resonance of that bell,” said Holler. “In this case the virus that you put onto the sphere is the chewing gum and the sphere is the bell.”

Last summer, Holler and the NYU Poly/CUNY team added gold nanoparticles to the sphere to create even smaller “hot spots.” It further increased the sphere’s sensitivity and enabled them to measure a single sample of the world’s smallest known RNA virus. The breakthrough was published in the July 30 issue of Applied Physics Letters.

Holler expects further breakthroughs, including a method of detecting protein that appears concurrent with certain cancers. Because of the sphere’s hypersensitivity, his hope is that it will be able to detect cancers earlier than current methods can.

Holler said that Fordham’s own whispering gallery biosensor should be completed later this summer, after which he plans to team up with Patricio Meneses, Ph.D., associate professor of biology, who has spent the last decade working on the human papillomavirus, or HPV.

“I have been working in this area for 10 years, so in about five years it would be nice to see the research commercialized, and of some benefit to those health professionals doing medical diagnostics,” said Holler.
