Biological Sciences – Fordham Now https://now.fordham.edu The official news site for Fordham University. Mon, 16 Dec 2024 15:54:59 +0000 en-US hourly 1 https://now.fordham.edu/wp-content/uploads/2015/01/favicon.png Biological Sciences – Fordham Now https://now.fordham.edu 32 32 232360065 Bird Deaths from Window Collisions Are Undercounted, Researcher Says https://now.fordham.edu/science/bird-deaths-from-window-collisions-are-undercounted-researcher-says/ Wed, 07 Aug 2024 20:42:07 +0000 https://now.fordham.edu/?p=193335 Every year, over a billion birds collide with buildings around the country. An estimated 600 million die immediately or succumb to their injuries on the ground.

But what about the birds that are rescued and brought to wildlife rehabilitators? In August 2021, Ar Kornreich, a Fordham biology Ph.D. student who is working on a dissertation about catbirds, began investigating how many of those birds also succumb. 

“I knew not all birds die immediately, and I wondered if there had been any research on birds that make it for a while before they die,” said Kornreich, who uses they/their/them pronouns.

“It just seemed like a no-brainer that states should have that info.”

In fact, Kornreich discovered that there is no one place where one can easily access this information. So they filed Freedom of Information Act (FOIA) requests with eight state agencies tasked with regulating the wildlife rehabilitators. They requested records regarding avian building collision cases between 2016 and 2021. Eventually, they received responses from six states, Washington D.C., and several privately run rehabilitators.

Findings

Kornreich and their co-authors published their results on Aug. 7 in the paper “Rehabilitation outcomes of bird-building collision victims in the Northeastern United States” in the journal PLOS ONE.

Ar Kornreich

They and their co-authors found that of the 3,033 birds that were rescued in these areas, about 60% didn’t ultimately make it: 974 died during treatment, while 861 had to be euthanized. The data also revealed that birds were injured more often during the autumn months, and concussions were the most common injury. 

These numbers—and the estimates that can be drawn from them—suggest that bird collision deaths far exceed one billion each year in the U.S., the paper says.

“There’s a huge blind spot in those birds that hit buildings and survive, at least for a little while, and looking at rehabilitation data can help remove that blind spot and help us make more informed decisions about conservation and preventing window collisions for bird populations,” Kornreich said. 

There are gaps in the data. The State of New York refused to release the data for all 62 counties in the state, for instance, so Kornreich limited their request to 10 counties in the New York metropolitan region. 

The data also came in formats as varied as PDF files and handwritten pages that needed to be painstakingly transcribed. What had initially seemed like an easy project that could be done while the world was on lockdown during the pandemic turned out to be anything but, said Kornreich. 

“It was funny; I had to buy the state of Pennsylvania a USB drive so that they could send me all of their data,” they said, laughing.

“I completely underestimated how much work it was going to be.”

Working with a Fordham Grad

To help make sense of the data, Kornreich partnered with Mason Youngblood, a postdoctoral fellow in the Institute for Advanced Computational Science at Stony Brook University. Dustin Partridge, Ph.D., GSAS ‘2020, from the NYC Bird Alliance, and Kaitlyn Parkins, GSAS ’15, from the American Bird Conservancy, served as advisors and co-authored the paper.

Kornreich said they’re hopeful that this research will help wildlife rehabilitation improve their desire and ability to share information. Just as hospital administrators share data on how patients fare after entering their doors, so too should wildlife rehabbers be open, they said.

“There is a very active community of rehabbers who are constantly swapping information and doing their best to make sure that their triage is data-driven and they’re using the most successful treatments,” they said. 

“But sometimes the rehab, scientific, and policy community’s transmission of information isn’t the most efficient. Some people in the scientific community look down on rehabbers and say they’re not really making a statistically significant difference, but I think that they are. They’re on the front lines of this crisis, so it is important to get their data and their viewpoints into this conversation.”

Advice from a Med School-Bound Fordham Senior https://now.fordham.edu/colleges-and-schools/fordham-college-at-rose-hill/advice-from-a-med-school-bound-fordham-senior/ Mon, 13 May 2024 18:02:14 +0000 https://now.fordham.edu/?p=190283 Rebecca Tejiram has always been fascinated by science, particularly the human body and its interconnected systems. Through the coursework for her major in biological sciences—as well as hospital volunteer work she did in high school— she discovered her love for medicine. 

A graduating senior and valedictorian at Fordham College at Rose Hill, Tejiram was accepted to three medical schools. She’s planning to attend the Icahn School of Medicine at Mount Sinai in Manhattan next year. 

“Medicine is so much more than just the [coursework]—there’s a heart to medicine,” she said. “It involves bonds of compassion; you’re there for somebody, and not only just to be there to feel with them, but to do something about it.”

Ahead of graduation, Tejiram, who is on the pre-health track, shared some advice for students interested in medical school. 

Explore unique research opportunities—when you’re ready.

Tejiram didn’t start working in a lab until her sophomore year, which she said allowed her to adjust to college and better understand the science behind the research.

Since then, she’s worked on two different research projects. She studied diseases such as age-related blindness in the vision lab of Silvia Finnemann, Ph.D., where she worked on a project that tests treatments for mice with vision defects. 

She also worked with Rachel Annunziato, Ph.D., on a clinical research project at Elmhurst Hospital in Queens—her hometown. The project aimed to engage at-risk patients and reduce medicine avoidance.  

“For some patients, I’ve been able to see them from the beginning to the end of the study, which has been really great,” she said. “I’m really excited to see the impact.”

Rebecca Tejiram is the valedictorian for FCRH.

Look for lessons that translate. 

In both research projects, Tejiram said she was looking for lessons that “can be easily translated” for medical school.

“For example, I do live tissue imaging,” she said. “It’s taught me how to balance precision and also time efficiency because you have a short window of time to work with the tissue. I think that’s going to be really important going into the fast-paced environment of medicine.”

Through her work at Elmhurst Hospital, Tejiram said she’s gained strong patient skills. 

“Being able to sit with them and talk with them and hear their stories—I think I’m going to need that … so they can trust me as their physician,” she said. 

Make a plan for applying to med school.

Tejiram said that the application process lasted about a year, so planning things like coursework and when to take the Medical College Admission Test (MCAT) was essential. Fordham advisors helped her navigate the process.

“I started applying in junior year—I had to take the MCAT, and then I had to do the primary application,” she said, noting that schools also send a secondary application. 

She spent last summer writing essays and submitting secondary applications before interview season started in the fall. She got her decisions starting in February. 

Rebecca Tejiram

Expand your studies beyond your major courses. 

Tejiram minored in bioethics, an area she discovered after taking a philosophical ethics course through Fordham’s core curriculum

“I realized how many ethical dilemmas come up in daily life, but especially in a field where you’re dealing with patients and human lives,” she said. 

Find supportive mentors and ask them for guidance.

When she was deciding if she wanted to go straight into medical school or take a gap year, Tejiram said she relied heavily on the advice of her Fordham mentors. 

“Those mentors, those support networks I found have been so instrumental throughout my whole journey, and I think it’s really important to remember that you don’t have to do it alone,” she said.

Remember, on the evening of May 18, New York’s Empire State Building will be illuminated in Fordham maroon for our graduates.

Exploring What Fascinates You: Rose Hill’s Undergraduate Research Symposium https://now.fordham.edu/colleges-and-schools/fordham-college-at-rose-hill/exploring-what-fascinates-you-rose-hills-undergraduate-research-symposium/ Wed, 24 Apr 2024 20:44:00 +0000 https://now.fordham.edu/?p=188807 From aggressive pigeons to the role of Haitian Vodou in confronting the shared trauma of slavery, hundreds of student researchers examined topics that ‘fascinated’ them, displaying their work at the annual Fordham College at Rose Hill Undergraduate Research Symposium on April 17.

Aggressive Pigeon Behavior: Bridget Crosby, Taylor Goche, Cream Sananikone, and Van Tran

Going to school in New York City made these four biological science majors “fascinated by pigeons.” “I’ve noticed particularly how close pigeons get to us, how they’re foraging for food, how they’re really never alone,” Crosby said. “I’m just fascinated by pigeons, especially in Manhattan, in comparison to more suburban areas. We wanted to see whether there was a correlation between the aggressive behavior and the location that they live in.” Working with the Ecology Lab at Fordham, the team spent hours in four parks analyzing pigeon behaviors. They found pigeons were more aggressive in the urban parks—Bryant Park and Washington Square Park, compared to the more suburban parks—Van Cortlandt Park and Crotona Park, concluding that pigeons in more urban areas are more accustomed to traffic and people, prompting them to act more boldly.

Mental Health in Literature: Marianna Apazidis

A senior from Massachusetts who is double-majoring in psychology and English, Apazidis united her academic interests through research that examined the portrayal of mental health in literature, particularly in Wide Sargasso Sea by Jean Rhys. The novel centers on a protagonist often considered to be schizophrenic in literary interpretations. Apazidis received a summer research grant that allowed her to visit the Jean Rhys archives in Tulsa, Oklahoma. There, she conducted empirical research, first-hand interviews, and archival research to investigate why the novel’s protagonist is often diagnosed this way and whether this is an accurate portrayal of psychosis. “I started with psychology because I’ve always been interested in how people work and what makes them who they are,” she said. “I quickly found that English is a very similar parallel discipline. I think literature is one of the most important ways to study human nature.”

Detecting the Presence of Metals in Water: Eva Riveros

Riveros was drawn to chemistry as a tangible way to find environmental solutions. Her research project involved the development of a Thiazole probe—a solution that uses proton transfer and fluorescence to detect the presence of metals in water samples. Riveros hopes to eventually create strips using the solution that can be used more easily and efficiently. “One of the main applications we’re thinking of is drinking water, so safety,” said the junior from New Jersey. Riveros developed her love of research after completing the ASPIRES program, which gives incoming students practical exposure to labs and hands-on experimentation.

Religion as Rebellion: Christopher Supplee

Supplee’s interest in how shared narratives shape cultural experiences led him to research the role of Haitian Vodou in confronting the shared traumatic experience of slavery. Supplee applied the three-part trauma recovery theory from Dr. Judith Herman, a leading expert on trauma, as a basis to examine the migration of Vodou from Haiti to the United States. “I look at how the enslaved population used [the practice of]voodoo as a means of maintaining their humanity under the dehumanizing conditions of slavery and rebuilding the community bonds that were separated through the TransAtlantic slave process,” said Supplee, an English and theology major from Philadelphia, “but also making new ones as a result of the diverse peoples that were coming from or transported from the African continent,” he said.

20 in Their 20s: Sonola Burrja https://now.fordham.edu/fordham-magazine/20-in-their-20s-sonola-burrja/ Fri, 08 Dec 2023 16:10:32 +0000 https://news.fordham.sitecare.pro/?p=179939

A Visa lottery winner finds her path to medical school

Growing up in Albania, Sonola Burrja never imagined that she would move to Mamaroneck, New York, and study in the United States. But when her family won the U.S. government’s Diversity Immigrant Visa program lottery in 2018, the plan changed.

“The plan was that my younger brother and I get educated outside of Albania, which would probably result in our … not going back, [but]when we won the U.S. lottery, my parents saw it as a great opportunity for the entire family to stay together,” says Burrja, who graduated from Fordham College at Rose Hill in May.

Now, just five years after moving to New York, she’s a first-year student at Albert Einstein College of Medicine in the Bronx. And she can’t imagine not having gone to Fordham, where she joined the pre-health program, majored in biological sciences, minored in German, and was part of the University’s inaugural group of ASPIRES scholars. Partially supported by the National Science Foundation, the program—which stands for Achievement in STEM through a Program of Immersive Research Experience and Support—provides a select group of undergraduates with scholarships for their four years at Fordham, guidance in and out of the lab, and funding for their undergraduate research. 

Conducting Ethical Research

Through ASPIRES, Burrja began collaborating with professors and conducting research almost right away—albeit not in the way she expected. It was March 2020, when COVID-19 spread to the United States, so her plan to conduct in-person research had to be put on hold in favor of a virtual research project.

“I was supposed to meet up with a researcher at Fordham that week that everything got shut down,” she recalls. Instead, she spent the summer working with Rachel Annunziato, Ph.D., a psychology professor and associate dean for strategic initiatives at Fordham College at Rose Hill, studying statistical data on diabetes and COVID-19 comorbidity.

Burrja went on to earn three undergraduate research grants from Fordham to support her work with biology professor Marija Kundakovic, Ph.D. She joined the Kundakovic Lab to study the epigenetic effects of hormones in female brains. 

“I never knew that there were so many differences between female and male brains—and that somebody at Fordham was actually tackling this issue,” Burrja says, explaining why she asked Kundakovic to be her mentor. “I really thought it was very interesting because some conditions, for example, depression and anxiety, have a sex bias of females during their reproductive stage. There are some huge differences, and we still don’t know enough about this topic—and the brain generally is a very unexplored area.”

To help her navigate the ethical questions that need to be taken into consideration when conducting research, Burrja took Ethics and Research, a course that allowed her to “discuss some very difficult dilemmas” and think deeper “about some issues that don’t really come into our lives, but if you go into medicine or if you go into actually doing research, those issues might come up—and there are actual consequences to being on one side or the other.”

And they will come up: Burrja plans to become a doctor. She’s not yet sure what her specialty will be, but one thing in particular is a must.

“The patient interaction part is something that I would not want to sacrifice,” she says. “I would like to be able to speak with them and just be an advocate for them, especially working with underserved populations.”

Student Biologist Studies Fruit Flies, Invasive Plants, and Sea Turtles https://now.fordham.edu/colleges-and-schools/fordham-college-at-rose-hill/student-biologist-studies-fruit-flies-invasive-plants-and-sea-turtles/ Thu, 09 Mar 2023 00:15:23 +0000 https://news.fordham.sitecare.pro/?p=170165 Stefania Bonanni, a junior at Fordham College at Rose Hill, has studied heart disease in fruit flies, the spread of an invasive plant species, and sea turtle conservation. 

“I haven’t pinpointed what I specifically want to work on, but I’m eager to do research that has some kind of positive impact on the world, whether that’s helping people or the environment,” Bonanni said. “I want my research to have a bigger purpose.”

Some student researchers focus on a single topic, but Bonanni has dabbled in several—and because of this, she sees the world differently, said a Fordham professor. 

Her experience has given her a good view of different topics. She can ask questions that other people might not be thinking about,” said her academic advisor Patricio Meneses, Ph.D., associate professor of biological sciences. “This will benefit her when it comes to asking the next interesting or necessary question in science.” 

‘A Whole New World Opened Up’ 

Bonanni was born to a family of scientists in Niskayuna, New York. Her father is an electrical engineer at General Electric. Her mother, a longtime optometrist, pursued her career when there were few women in her field. Both inspired their daughter to become a researcher. 

Bonanni had always been fascinated by the natural world. In elementary school, she drew three-page pictures of different landscapes and the flora and fauna that lived within them. But in high school, Bonanni realized that science was more than a childhood interest. 

“When I took a biology course, it was like a whole new world opened up. I learned how the natural world works, how everything fits together in ecosystems, and how life functions. Once I knew that was a field, I was like, ‘Wow—that’s the one for me,’” she said.

Growing as a Biologist at Fordham

In 2020, she enrolled at Fordham. She wanted to attend school in New York City, and she was drawn to Fordham’s Jesuit ideals.

“I knew that I could find a Catholic community at other colleges, but I liked how Fordham implements the Jesuit values in their course philosophy,” she said. 

Bonanni spent her first year on Zoom due to the pandemic. The following summer, she took two tuition-free classes. Among them was a genetics course with biology professor Edward Dubrovsky, Ph.D., whose work she loved so much that she asked if she could work in his lab. 

Throughout her sophomore year, they examined the genetic mutations responsible for cardiomyopathy, a disease that thickens heart tissue and can lead to death. Using fruit flies as a model for the human body, they explored a question: Where do the mutated genes that cause cardiomyopathy need to be located in order for symptoms to develop? Any cell in the body or specifically in the heart? (They later learned that the latter was correct.)

Under Dubrovsky, Bonanni learned what it’s like to work in a real lab, versus a classroom. 

“When you’re in a research lab, you don’t know what the answer is. Sometimes things don’t go right the first time, but that’s just part of the research process,” Bonanni said. “That uncertainty is where discoveries are made.” 

The following summer, she studied in Australia through Fordham’s partnership with the School for Field Studies. For one month, she lived in the rainforest and conducted fieldwork on marsupials. 

“It was really cool to learn about how they came to be in Australia and set up field cameras to take pictures of marsupials passing by, like pademelons,” Bonanni said. 

Exploring Bronx Plant Life

She loved working with animals, but she also wanted to try working with plants. She had always enjoyed tending to her family’s vegetable garden, where they raised tomatoes, lettuce, squash, and beans. 

Last fall, she studied the spread of Japanese knotweed, an invasive species that has spread to the Bronx, in the lab of biology professor Steven J. Franks, Ph.D. She enjoyed the experience, but realized she preferred working with animal cells.

Keeping the Earth Safe for Turtles

This semester, Bonanni started working on a project that combines her interests in cell and molecular biology and ecology. 

In the lab of Evon Hekkala, Ph.D., associate professor of biological sciences, Bonanni is studying green sea turtles, the largest hard-shelled sea turtle on Earth. Every year, these turtles return to the same beach to lay their eggs. The problem is only some areas are protected from poaching and other activities that prevent babies from hatching and safely making their way to the ocean. 

“If only specific areas are protected, then only specific turtle genes might be protected. That means you’re limiting the genetic diversity of the population,” Bonanni said. “A less genetically diverse population is less likely to survive diseases,” said Bonanni, who is now analyzing DNA from hatched turtle shells to assess their genetic diversity. 

The Wonder of the Natural World 

Bonanni wants to become a biologist. No matter what she focuses on, she says she wants to hold onto something that we often forget as adults—the wonder of the natural world. 

“Growing plants is so exciting when you really think about it,” said Bonanni, who once worked as a summer camp counselor who taught children how to water seeds into sunflowers. “The fact that a beautiful, green, lush thing can come out of a small seed is so cool. As adults, we sometimes lose the wonder associated with that. But when you look at a kid experiencing it for the first time, you remember how exciting it really is.”

Neuroscientist Awarded NIH Grant to Study Impulsive Behavior https://now.fordham.edu/science/neuroscientist-awarded-nih-grant-to-study-impulsive-behavior/ Tue, 13 Dec 2022 21:51:53 +0000 https://news.fordham.sitecare.pro/?p=167323 Eduardo Gallo, Ph.D., an assistant professor in biological sciences, is trying to understand how an overlooked group of brain cells can control our impulses. His research, recently funded by a nearly $2 million research grant from the National Institutes of Health, could eventually contribute to the development of treatments and prevention methods for people with substance use and mental health disorders. 

“I am inherently curious about how our body operates, especially the brain,” said Gallo, whose lab was awarded the five-year NIH grant this summer. “But I’m also very interested in science because of its power to create knowledge that could help people.”

Gallo is a Honduran-American neuroscientist. At age 18, he earned a scholarship to study in the United States. He became the first in his family to leave Honduras to pursue a college education in the U.S. (Gallo is not the first family member to work in STEM, however—his father is a civil engineer.) He went on to earn his bachelor’s degree in biological sciences from the University of New Orleans and his Ph.D. in neuroscience and neurophysiology from Weill Medical College of Cornell University. For the next seven years, he worked in Columbia University’s psychiatry department, where he started as a postdoctoral fellow and then progressed to postdoctoral research scientist, associate research scientist, and assistant professor of clinical neurobiology. 

A smiling man raises his arm up and smiles.

How Does Our Brain Control Our Motivations? 

In 2018, he became a faculty member at Fordham. He currently teaches cell biology to undergraduates at Fordham College at Rose Hill and students in the Graduate School of Arts and Sciences. In addition, he runs his own research lab on the second floor of Larkin Hall, which is devoted to understanding how our brain controls our motivated behavior. 

“What, in our brains, drives our desire to pursue rewarding things? What cells are important for making us willing to work hard at something? For weighing the costs and benefits of a potential decision?” Gallo said. “The goal of our lab is to pinpoint what cells in our brains are critical for some of these behaviors.” 

Scientists have already identified many brain regions that are involved in these behaviors, said Gallo. But they haven’t identified the individual cell types that are related to motivation, especially in the context of impulsivity.  

“Let’s compare this to a car engine. We know the engine is important for the car to run, but how do the individual components in that engine make it function? Our job in the lab is to try to understand the components of that engine—or those key brain cells—and how they work together,” he said. “Once we have enough knowledge about those specific cells, then one day, someone can design therapies that go right to the problem.” 

Understanding Our Impulsive Behavior in the Lab

In his new project funded by the NIH grant, Gallo is studying a small population of brain cells that is often overlooked: cholinergic interneurons. They make up about 2% of all brain cells in a key reward brain region. However, they have a wide range of control of neighboring cells, he said. 

Gallo’s project will tackle several key questions: Are these cells important for a specific motivated behavior—impulsive decision-making, a common trait of people with substance use disorders and other mental illnesses? If so, what is their genetic makeup? And how do these cells function while impulsive behavior is taking place? 

His team will investigate these questions using mice, which are able to make decisions about rewards and be impulsive, just like humans.

“We’re interested in how certain drugs can affect our brain processes to make us more impulsive. They can also cause impulsive behavior and a lack of decision-making abilities. Excessive impulsivity can seriously affect our health, from risky sexual behavior to how much we eat, or whether we take our medications. So if we can fully understand how the brain and all its cells work, in relation to impulsive behavior, then we might be able to target many different problems at once,” he said.

Brain Research Relevant to the Bronx and Beyond

Gallo said that his research can seem inaccessible—a part of the “ivory tower” of academia. Even the title of his research project, “Cholinergic Interneuron D2 Receptor Function in Impulsive Behavior: Implications for Addiction,” sounds complicated. But his research has the potential to affect millions of people, he said. 

“The subjects that we study—mental illness, substance abuse disorder—are very relevant to our local community here in the Bronx and in New York,” said Gallo, who lives in Washington Heights with his wife and their two daughters. “Illicit drugs are inflicting harm on our health system right now. In the past, these disorders have been treated as a scourge on society. We have blamed people for not wanting to get better, but it’s really not their fault. Our brains are wired in a specific way, and drugs can make it difficult for us to resist addiction. We need to create better treatments and strategies that help people with these disorders.”

He credited his Fordham research team, which is largely made up of undergraduate and graduate students from the biological sciences and integrative neuroscience programs, with helping him reach that goal. In return, they helped him realize something about himself. 

“Mentoring younger generations is one of my favorite things about being here at Fordham. Some of my students may not know for sure that they want to pursue a career in science, but I enjoy inspiring them,” Gallo said. “Sometimes they don’t realize that they want to be a scientist—or that they even can. I hope to inspire them to pursue meaningful careers in solving the mysteries of the brain.”

Postcard from Yellowstone Country: Rams, Raptors, and ‘Raw Nature’ https://now.fordham.edu/fordham-magazine/postcard-from-yellowstone-country-rams-raptors-and-raw-nature/ Thu, 22 Jul 2021 17:38:41 +0000 https://news.fordham.sitecare.pro/?p=151866 Drive west from Cody, Wyoming, and you might spot bighorn sheep leaving Shoshone National Forest—a lamb and ewe trotting across the highway, rams butting heads on the asphalt. “We’ll see them pretty regularly, and that always ties me back to Fordham a bit,” Corey Anco, GSAS ’16, said of the rams, the University’s mascot.

After earning a master’s degree in biology at Fordham five years ago, Anco moved to Wyoming to serve as assistant curator of the Draper Natural History Museum, part of the Buffalo Bill Center of the West in Cody. The museum, about 50 miles east of Yellowstone National Park, features a live raptor education program and introduces visitors to the sights, sounds, and smells of the region’s diverse ecosystems, from alpine to mountain meadow to plains.

Anco hadn’t considered museums as a career path until he worked closely with Fordham biology professor Evon Hekkala, Ph.D., conducting genetic research using historical African leopard specimens at the American Museum of Natural History. Beyond their educational mission, he realized, museums are “actively involved in research and, in some instances, conservation action.”

That’s what drew him to the Draper museum, which Anco said has been monitoring the occupancy, distribution, reproduction, and diet of golden eagles in the Bighorn Basin since 2009. He said he’s humbled and inspired by his work and where he does it.

“When I climb over a ridge and see how expansive this alpine landscape is, and that there’s literally no sign of human impact for miles and miles and miles, I get such a visceral feeling of raw nature that inspires me to care for it.”

Devin Rocks is still at least a year away from earning his Ph.D. in biology. But the Rockaway Park, Queens, native is already making a splash in the academic world, thanks to his work examining the role that fluctuating sex hormones can have on mental disorders such as anxiety and depression.

This spring, the Organization for the Study of Sex Differences honored Rocks with the Elizabeth Young New Investigator Award, and the Society for Behavioral Neuroendocrinology awarded him its Welcome Initiative Award. In January, the Society for Neuroscience bestowed upon him the Trainee Professional Development Award.

The awards recognize both the promise that Rocks has as a scientist and the work he’s conducted at Fordham under the guidance of Marija Kundakovic, Ph.D., assistant professor of biology. Kundakovic’s lab has been focused on an acute problem: Women are twice as likely to have anxiety and depression than men, but little research has been done on the molecular level to figure out why—until now. In January, Kundakovic was awarded nearly $1.9 million in grant funding from the National Institute of Mental Health for her research.

Rocks, who graduated from Fordham College Rose Hill in 2017 with a B.S. in integrative neuroscience and is on track to earn a Ph.D. in biological sciences in 2022, has been a part of the research from the beginning. He was one of five co-authors of a 2019 paper published in the prestigious journal Nature Communications that showed how a microscopic cell component called chromatin changes its shape during the mouse ovarian cycle—especially when females experience a change in estrogen. Because the changes occur inside the brain area implicated in anxiety and depression, it may affect women’s vulnerability to an increased risk for these disorders.

“The chromatin is basically the packaging material of the DNA. The chromatin can either be open, which allows the genes to be turned on, or it can be closed, in which case the genes are turned off,” he said.

“The studies showed that, over the rodent estrous cycle, which is the rodent equivalent of the menstrual cycle, the fluctuating sex hormones are affecting whether this chromatin is open or closed and affecting certain genes.”

It’s not known exactly how the opening or closing of chromatin causes depression or anxiety, but connecting the two events together is an important step in the research.

Since that 2019 paper was published, Rocks has been conducting follow-up research that involves introducing a gene known as Egr1 into the brains of laboratory mice to mimic the changes that normally only happen during the estrous cycle. The results will be published as part of his dissertation.

“We can give mice extra copies of this gene in the brain region that we study, the ventral hippocampus, and this can mimic the effect you’d see from the fluctuating hormones. This gene seems to be playing an important master regulatory role,” he said.

Kundakovic, who joined Fordham in 2015 and began working with Rocks when he was in his junior undergraduate year, said “functional” studies that rely on live animals are vital to verifying studies that use computational analysis to predict whether one change (a change in estrogen) is connected to something happening in the brain (a change in chromatin structure) and behavior.

“You can do a big data-computational type analysis, and say, ‘Give me the predicted regulator of these chromatin changes that we are seeing.’ [In 2019], we did that, and we found a really good candidate in Egr1,” she said.

“What Devin did was he took the candidate that we have, and he was able to do a manipulation of the animals in which he could functionally relate the changes and say, ‘This is the regulator of the behavior.’”

Rocks still has more research to do. Now that he knows that introducing Egr1 into mouse brains can change their behavior, he’s planning to conduct experiments that show exactly how Egr1 affects chromatin.

“We want to see which changes in chromatin and gene expression that we see happening in normal animals over their estrous cycle are being regulated directly by Egr1,” said Rocks, who also teaches techniques in molecular biology to first-year graduate students.

The awards he received are gratifying, he said, given that he’s still completing his education.

“It’s an indication that the community is welcoming me as someone who will contribute to the field in the future and will continue to grow as a scientist, and so I’m really grateful for all of them,” he said.

The most challenging aspect of the research has been utilizing the full spectrum of research techniques required.

“A lot of labs will just do one of the techniques we do, like the genome-wide experiments. Learning how to do them and analyze all that data that comes out of it using bioinformatics analysis, and then also learning how to do animal surgeries—we combine so many different disciplines and techniques,” he said.

“It’s definitely been a challenge to keep up with all of that. It’s also really exciting though. Learning new things is one of my favorite parts of the job.”

Kundakovic was quick to note that when it was announced that Rocks had won the Elizabeth Young New Investigator Award, he was introduced as a “future leader in the field.”

“As someone who’s been working with him for the past five years, since he was an undergraduate, it’s really been my privilege to watch him grow as a person and a scientist,” she said.

“His dedication to his work, his passion; it’s just paid off really well. I think he’s on a really good path.”

$1.9 Million Grant Will Fund Research on Women’s Mental Health https://now.fordham.edu/colleges-and-schools/graduate-school-of-arts-and-sciences/1-9-million-grant-will-fund-research-on-womens-mental-health/ Mon, 15 Feb 2021 05:15:25 +0000 https://news.fordham.sitecare.pro/?p=145517 Marija Kundakovic, Ph.D., assistant professor of biological sciences, was awarded nearly $1.9 million in grant funding from the National Institute of Mental Health for her neuroscience research on women’s mental health. 

“The field of neuroscience has been very male-centric. Most studies were historically done on males, and there wasn’t enough information on the female brain in general. This grant is not only a testament to the excellence of the project proposal, but also to the importance of this topic,” said Kundakovic, who learned she received the grant on Jan. 29. 

Kundakovic studies cellular changes in the brain on a molecular level using a mouse model. Her lab specializes in researching the molecular mechanisms behind hormonal changes during the ovarian cycle and how they can change female brain and behavior. Her research results could lead to the development of sex-specific treatments for mental disorders like anxiety and depression—disorders that are more prevalent in women than in men. 

In recent years, Kundakovic and her team discovered that chromatin, a microscopic cell component, changes its shape during the ovarian cycle, which also changes the way genes are expressed. Over the next five years of grant funding from the NIMH, they will build on their research and try to better understand how chromatin changes in brain cells can impact anxiety-related behavior, especially for female mice, in her project “Epigenetic regulation of brain and behavior by the estrous cycle.” 

“We are trying to understand how chromatin changes within brain cells affect cellular function and contribute to changes in behavior and which specific cells are really critical for changing behavior,” said Kundakovic. “With this new grant, we will be able to identify the specific brain cells that are really responsive to hormonal changes and reveal epigenetic regulators that are possible targets for drug treatment.”

Kundakovic said her research has taken on new meaning during the pandemic, an unprecedented period where more people than usual are struggling with their mental health, especially anxiety and depression. 

“The pandemic may widen the gender gap that we are already seeing in anxiety and depression,” Kundakovic said. “We will have even more women who are affected by these disorders.”

“One of the things I am the most grateful for from my experience at Fordham was actually learning about things not related to my major. Since we are required to take the core curriculum, I was exposed to so many different classes I never would have taken otherwise. These courses refined the way I think about virtually everything. Buddhism in America helped me discover my interest in Buddhism, and Intro to Bioethics challenged many preconceived beliefs I had about the health care industry and controversial ethicists.”

A Day in the Wildlife: Among the Ecosystems and Ecologists at the Calder Center https://now.fordham.edu/fordham-magazine/a-day-in-the-wildlife/ Fri, 26 Jan 2018 17:18:37 +0000 https://news.fordham.sitecare.pro/?p=84287

At the Louis Calder Center, scientists explore ecological mysteries and study society’s impact on the natural world.

To the casual observer, Fordham’s Louis Calder Center might seem to be just another quiet tract of Hudson River Valley forest. But for natural scientists, it abounds with opportunity. Explore the 113-acre biological field station in Armonk, New York, and you’ll find a bounty of ecosystems and animals, from the four-legged to the microscopic. At the heart of the preserve is a 10-acre temperate lake teeming with a diversity of aquatic life. Go high enough and, way off in the distance, you can see another big player in the preserve’s ecology: New York City, which begins only 16 miles away.

Its proximity has never been more relevant. “Humans and our cities are the most dominant forces of contemporary evolution now,” says Jason Munshi-South, Ph.D., a Calder-based biology professor who recently co-authored a paper in the journal Science on how species are evolving within cities. Other scientists at Calder study invasive species that arrive via big-city commerce. And they tackle many other mysteries: why some animals survive new threats while others don’t, how nutrients flow beneath the soil, or how insects transmit disease.

The center was born 50 years ago when the land was given to Fordham by the Louis Calder Foundation, named for the paper and pulp magnate who maintained a summer home on the property. Today, that home is Calder Hall, one of several buildings in which students and professors analyze DNA samples, inspect plant and animal specimens, hold classes, and generate knowledge.

Among many other public services, the Calder Center supports the nation’s longest-running study of ticks and Lyme disease, and its scientists work to illuminate society’s impact on nature at a time of growing concern about biodiversity and climate change.

It is also a crucial training ground: “The most important thing we do here is make scientists,” says Thomas Daniels, Ph.D., an expert in tick- and mosquito-borne diseases who has served as the center’s director since 2014.

On a sparkling autumn day late last October, FORDHAM magazine tagged along as undergraduates, graduate students, professors, and visiting scientists went about their work—gently probing, collecting samples, and explaining the science behind their work and its potential impact.

Evolution in the Big City

In recent years, Fordham biologist Jason Munshi-South, Ph.D., and his team of graduate and undergraduate students have become known for their studies of urban wildlife and pest species, most notably rats.

“The initial idea was to understand what a New York City rat is, from all ecological and evolutionary angles,” he says of one project, which grew to a global scale and has public health implications. “We’re using DNA to understand how they move around the city and how they’re related to other rat populations.”

In a first-floor lab in Calder Hall, doctoral student Carol Henger uses similar methods to study coyotes, animals that only recently moved into the city for the first time, Munshi-South says. She’s looking at DNA markers from coyote scat collected in Pelham Bay Park and elsewhere to infer how individual coyotes are related, what they’re eating, and how they’re dispersing.

Meanwhile, Nicole Fusco, another doctoral student in Munshi-South’s lab, sequences DNA to study gene flow among populations of salamanders.

Biodiversity and Climate Change

In the Calder Center’s Lord & Burnham greenhouse, constructed on the property nearly a century ago, doctoral student Stephen Kutos has been growing pairs of potted trees and studying how they pass water and nutrients back and forth via subsoil networks of fungus.

“Tree stumps have been found that are still alive hundreds of years after the tree was cut down, quite possibly because surrounding trees send them nutrients,” he says. With further study, he adds, it may be possible to restore the wild population of one type of tree he’s growing, the American chestnut, which was eradicated from the wild 100 years ago by blight.

Restoring the tree could help combat climate change, scientists believe, because the American chestnut can absorb and store carbon quickly.

In an adjacent greenhouse, several researchers work on an evolutionary study initiated by Fordham biologist Steven Franks, Ph.D., and focused on Brassica rapa (field mustard). As Franks demonstrated in an earlier study, the annual plant evolved earlier flowering within just five years to cope with drought conditions in California.

The Mystery of the Red-Backed Salamander’s Survival

Late in the morning, undergrads Dan Khieninson and Erin Carter and doctoral student Elle Barnes enter Calder forest in search of red-backed salamanders.

“You can find them anywhere in the forest as long as the soil’s moist,” Barnes says before the group navigates a steep decline to the forest floor.

She indicates several flat, weathered pieces of wood she’s left behind. “You’re more likely to find them under here.” The three researchers crouch down and soon locate several specimens.

They’re trying to discover why red-backed salamanders are not affected by the chytrid fungus that is devastating other amphibian populations.

“It’s not enough to just study the ones that are going extinct,” Barnes says. “There are solutions in the ones that will survive. What do they have that other amphibians are lacking?”

The answer lies in their microbiome, Barnes says. She, Carter, and Khieninson use cotton swabs on the salamanders’ bodies to collect samples of microorganisms that they can test against chytrid fungus in the lab. The impact of their research could extend beyond conservation biology, Barnes says: “The discoveries we make about disease and microbiomes can be applied to multiple systems, including humans’.”

A Closer Look at a Ubiquitious, Ecologically Valuable Species

Michael Kausch, a doctoral student in aquatic ecology, rows a boat out on Calder Lake to take some water samples he can later test for cyanobacteria at the lakefront McCarthy Laboratories. Meanwhile, inside the lab, his fellow doctoral student Stephen Gottschalk is working with their Fordham supervisor, John Wehr, Ph.D. Gottschalk is studying green algae in the Characeae family.

“They’re an important food source for birds, a habitat for insects, and they support fisheries,” he says.

So far Gottschalk has collected samples in nine U.S. states, and he’s been working at the New York Botanical Garden under the supervision of Kenneth Karol, Ph.D., to examine his samples on a molecular level.

He’s finding that what scientists once thought were just subtle differences among green algae are in fact ecologically important distinctions. “They’re designated as one species,” Gottschalk says, “but what it looks like to me so far is these are very regionally distinct.”

Mosquitoes, Ticks, and the Pathogens They Carry

Insect-borne diseases are a big part of the research focus at Routh House, the vector ecology lab at the Calder Center that’s jointly run by Fordham and the New York state health department. Inside the lab, scientists study samples of various species, such as the aggressive and potentially disease-carrying Asian tiger mosquito. Outside, they collect specimens and conduct surveillance projects.

“We set up mosquito traps all around the lower Hudson Valley,” says Marly Katz, a state employee and Fordham doctoral student. “All the mosquitoes end up here, where I identify them, and then we send a bunch [to the state health department]for disease testing.” She and her colleagues are also collaborating with Columbia University scientists to “map the Asian tiger mosquito,” she says, and determine if changes in climate are affecting its migration patterns.

While Katz checks a mosquito trap, research technician Richard Rizzitello collects ticks by dragging a white cloth across the ground and then pulling them off with forceps (he uses a lint roller to collect any larvae).

One Calder scientist, Nicholas Piedmonte, displays egg-to-adult samples of the blacklegged tick, which can carry the bacterium that causes Lyme disease.

“These are great for education and outreach,” he says, particularly in central New York, “where ticks are kind of a new problem.”
