Why a PhD in Clinical Research? One Student Discusses Her Trajectory Into Science

Jasmine Modasi, MSCR

First, there was an interest in studying medicine, but then a research project brought new possibilities to Jasmine Modasi, MSCR, a 2022 graduate of Mount Sinai’s Master of Science in Clinical Research program.

In the following Q&A, Ms. Modasi, who is now enrolled in the PhD in Clinical Research program, discusses recent achievements—and her aspirations to ultimately improve the lives of those living with psychiatric illness.

What attracted you to this area of study? 

My background is in developmental cognitive neuroscience and I am fascinated by the relationships among human experiences, development, cognition, the brain, and behavior. My initial plans were to go to medical school and specialize in psychiatry.

During my undergraduate thesis project, however, I had the opportunity to conduct a research study in language learning, totally unrelated to what I do now. Regardless, I thoroughly enjoyed the process and began to imagine that perhaps research was for me.

Mental health has always been very important to me and I felt I could make a greater contribution to the field by doing the research that ultimately goes into practice. As a longtime mental health advocate, I’ve heard concerns voiced by friends and fellow students, both for themselves and the community, and this continues to inspire me to strive toward improving our understanding and approaches to treating mental health problems.

What were some of your achievements as a master’s student? 

I had the opportunity to take on several roles as a research assistant, teaching assistant, and Trainee Health and Wellness (THAW) committee member. During my research, I produced an original manuscript for my thesis examining associations between chronic and acute lifetime stressors with psychosis-risk symptoms in high-risk genetic disorders—it has since been submitted to a peer-reviewed journal.

Outside of academics, I took on the role of co-host for the THAW Wellness Podcast where we aim to inform students and trainees of the many resources available at Mount Sinai through discussions with members of various offices and organizations, such as the Office of Career Services and the Office of Gender Equity. In recognition of my achievements and contributions, I was awarded the Outstanding Thesis Award and Excellence in Leadership and Service Award.

Why a PhD—What are your goals in the PhD clinical research program? 

The clinical research program has provided me with opportunities to explore the field and deepen my appreciation for the work underlying medical practice. Pursuing a PhD will only continue to better my understanding of how to design and conduct effective research studies to create meaningful contributions to medicine.

One major goal I have is to work closely with physicians to identify gaps in medical knowledge pertaining to disease etiology for developing and/or improving treatment and prevention methods. I am particularly interested in under-researched areas of psychiatric illness and symptoms of schizophrenia spectrum and borderline personality disorders.

As an evolving researcher, I hope my work will improve the lives of those living with psychiatric illness and advance medicine by bridging the gap between research and practice.

PhD Students Get Lab Coats, Marking the Start of New Journeys in Research and Training

Dozens of members of the 2022 PhD and MD/PhD matriculating class of the Icahn School of Medicine at Mount Sinai Graduate School of Biomedical Sciences were presented with lab coats in a celebratory event held Monday, September 19, amid the cheers and applause from the audience—which included faculty, mentors, and the students’ families and friends. Wearing their coats, the students would later take a vow, together, “to uphold the highest levels of integrity, professionalism, scholarship, and honor,” as they embarked on new scientific paths.

Marta Filizola, PhD

“We hold this ceremony to mark the start of our students’ journey in academic research and training,” said Marta Filizola, PhD, the Dean of the Graduate School of Biomedical Sciences and the Sharon & Frederick A. Klingenstein-Nathan G. Kase, MD Professor. “The lab coats we present to them are a symbol of the professionalism and authority that trainees develop and foster during their time in our programs,” added Dr. Filizola, who is also Professor of Pharmacological Sciences, Neuroscience, and Artificial Intelligence and Human Health. Mount Sinai offers PhD degrees in biomedical sciences, neuroscience, and clinical research, and a dual MD/PhD medical scientist training program degree, in addition to nine master’s program degrees.

Eric J. Nestler, MD, PhD

Eric J. Nestler, MD, PhD, Dean for Academic Affairs at Icahn Mount Sinai, and Chief Scientific Officer for the Mount Sinai Health System told the students: “Getting a PhD is hard work. There is no way around that. It’s hard work because PhDs—unlike all professional degrees, for example, an MD or law degree—require each of us to create a body of knowledge that is new to the world.” Still, he encouraged each not only to “work hard—but play hard,” adding, “Life must go on. No one should defer having a social life during their PhD studies.” Dr. Nestler is also Director of The Friedman Brain Institute and Nash Family Professor of Neuroscience.

A rousing keynote speech was presented by Xiaosi Gu, PhD, Associate Professor of Psychiatry, and Neuroscience, and Founding Director of the Center for Computational Psychiatry. Dr. Gu, a foremost researcher in the area of computational psychiatry, received her PhD degree in Neuroscience at Mount Sinai.

Dr. Gu shared her thoughts on curiosity, which she described as the one “secret Ingredient” capable of helping the students face the PhD journey, while making it enjoyable—and successful.

Xiaosi Gu, PhD

“Curiosity is the fundamental reason why you are still sitting here today instead of already working in a tech company, or Wall Street,” she began. “What should we be curious about? Be curious about science, be curious about people, and be curious about life.

“First, be curious about your work … you must love what you do,” she urged. “Be curious about people. A huge reason I feel pumped every morning going into the office is the people I work with. Face-to-face meetings, small talks in the hallway, grabbing lunch together, these are the daily doses of happiness that keep a day going.

“Finally, be curious about life. This, I believe, is the holy grail of curiosity … We, as scientists, have an obligation to stay curious about the real world and pursue work that can meet human needs … Staying curious about humanity and its issues might be the only way to unlock your intellectual potential and find your path.”

This was followed by a lively presentation of the lab coats, an effort sponsored by the Mount Sinai Alumni Association, and finally, the reading of the PhD Oath. “I will conduct my research and professional endeavors with honesty and objectivity,” they said in unison, while wearing their crisp white lab coats, and reciting a pledge to uphold a set of guiding principles as they launched their science training at Mount Sinai.

What makes this class special? This is who they are:

Mount Sinai Program Gives Underrepresented Students a Hands-On Lab Experience—and a Pathway to Graduate School

Fifteen college students who participated in a 10-week research program may each have had different interests—for example, cardiology, immunology, microbiology, neuroscience, oncology, or psychiatry. But as a group, they had one fundamental, unifying distinction. They were rising college juniors and seniors from racial or ethnic backgrounds underrepresented in biomedical science, and, together, on the campus of the Icahn School of Medicine at Mount Sinai Graduate School of Biomedical Sciences, they had an unparalleled opportunity to enhance their research skills and set a course for future careers.

The students performed basic research working alongside some of Mount Sinai’s top scientists, but they additionally learned skills beyond the lab—all part of a robust curriculum offered by the Summer Undergraduate Research Program for Underrepresented Scholars (SURP4US). The program, which was conducted from June 6 to August 12, culminated with a poster session, a public event where the students showcased their work.

“The goal of SURP4US is to train and mentor aspiring biomedical scientists or physician-scientists who are interested in obtaining hands-on research experience, enhancing their scientific knowledge and skills to ultimately strengthen their applications for PhD or MD/PhD programs,” says Hala Harony-Nicolas, PhD. “Students who join our program may have had very minimal prior research experience or may have already been equipped with an extensive research experience. We want to provide an environment in which each student can build upon their previous experiences to get one step closer to being ready for graduate school.”

Marta Filizola, PhD, Dean of the Graduate School of Biomedical Sciences, and the Sharon & Frederick A. Klingenstein /Nathan G. Kase, MD Professor of Pharmacological Sciences, Professor of Neuroscience, and Professor of Artificial Intelligence and Human Health, spoke to the students

Dr. Harony-Nicolas, who is Associate Professor of Psychiatry, and Neuroscience, and a member of the Seaver Autism Center for Research and Treatment, created and directed this year’s program and mentored one of the students.

“What is important and unique about our program is that the hands-on research training on campus is only one piece of the students’ rich summer experiences,” says Dr. Harony-Nicolas. “In parallel to this enriching training experience with our dedicated faculty, postdocs, and students, our students attended seminars about the latest techniques in biomedical research and visited our core facilities to learn about conventional and innovative technologies in biomedical sciences. They also had workshops on science communication and received training on how to put together graduate school applications and prepare for their interviews.”

Students also had the opportunity to meet deans, directors of graduate school programs, faculty members, postdocs, and students through several networking and social events to learn more about the biomedical research world in general and what it means to be a scientist, including how to balance a research career and life. Finally, being part of the program also provided the students with an opportunity for early admission to the Graduate School’s PhD and MD/PhD programs through the FlexGrad program, which is only offered to SURP4US participants.

“It is such a rewarding experience to see how excited and eager the students are to absorb the tremendous amount of knowledge they are offered within such a short time and to engage in scientific discussions and share their curiosity,” says Dr. Harony-Nicolas.

Read on to learn more about the scientific journeys, experiences, and goals of three SURP4US students.

Student Naomi Calhoun, right, in the lab with Emily Bernstein, PhD

Naomi Calhoun, Howard University, aspires to be a physician-scientist:

  • Her science journey: “As I explored different avenues in my academic journey, self-discovery in my identity was instrumental as I focused on research interests. When I realized how interconnected my identities were as a Black person and a woman, I knew I had to use my unique perspective to serve as a representative for others.

“Talking to my peers, I realized how much of a luxury it is to have Black women doctors for both pediatric and gynecological care. I like the comfort that comes with this equal identity of patient and doctor.

“This became pivotal as I shifted my research focus to the intersection of women’s health and biomedical engineering with the need to provide an equitable health care experience while understanding the challenges of the current health disparities among diverse groups of women.”

  • Where she worked: Lab of Emily Bernstein, PhD, Professor of Oncological Sciences, and Dermatology, where she was also mentored by Anisha Cooke, a PhD candidate in Biomedical Science.
  • What she worked on: Designing an inducible gene-editing system to investigate mutations in the ATRX gene commonly found in neuroblastoma cells in older children, and designing a protein-degrading system to degrade the mutated gene’s protein products.
  • What she accomplished: “Naomi entered the program with great enthusiasm and drive and quickly assimilated herself into our laboratory,” says Dr. Bernstein. “She became familiar with techniques ranging from DNA cloning to the culturing of tumor cells. Her project involved generating cells that have incorporated tightly regulated and inducible systems whereby we can toggle the expression or mutation of the ATRX gene, which is highly mutated in pediatric cancers, at the time point(s) of our choosing.”
  • What she learned: “I’ve learned resilience, that when lab experiments do not work out the way they are supposed to, I remind myself not to be discouraged. When things don’t go my way—in life or academically—I work to keep an optimistic mindset, and then I find a new way to approach the problem and keep pushing forward.”­– Naomi Calhoun

Student Kevin Medina, right, in the lab with Maria Curotto de Lafaille, PhD, and Weslley Fernandes Braga, PhD

Kevin Medina, SUNY Stonybrook, aspires to be a physician-scientist:

  • His science journey: “After I was born at The Mount Sinai Hospital, doctors discovered that I had an immune defect early on in life. Growing up in Harlem, I knew I was different from most kids because of my immunological condition.

“I recall profound confusion about my yearly clinical immunology visit with Dr. Cunningham-Rundles [Charlotte Cunningham-Rundles, MD, PhD, the David S. Gottesman Professor of Immunology, and Professor of Medicine, and Pediatrics]. However, the one thing that was always crystal clear was her infinite curiosity about my condition and her ability to allay my parents’ fears with her wisdom about the extensive research regarding my condition. Recently, after I had decided to pursue a career in medicine, Dr. Cunningham-Rundles offered me the opportunity to spend time in her lab. I realized how interconnected medicine and research were.

“Ultimately, my curiosity to answer interesting questions regarding immunological disease is all rooted in wanting to give back to the Harlem community that Mount Sinai serves. I have realized that if I am fortunate enough to achieve my goal of becoming a physician-scientist, I can advance the field of medicine by engaging in world-class research that can ultimately be translated into producing novel treatment modalities for communities like mine.”

  • Where he worked: Lab of Maria Curotto de Lafaille, PhD, Associate Professor of Pediatrics, and a member of the Elliot and Roslyn Jaffe Food Allergy Institute and the Precision Immunology Institute, where he was also mentored by postdoctoral fellow Weslley Fernandes Braga, PhD.
  • What he worked on: Identifying factors that regulate the production of immunoglobulin E (IgE) and immunoglobulin G4 (IgG4), important antibodies in human diseases such as food allergy and eosinophilic esophagitis.
  • What he accomplished: “The SURP4US program has given us the opportunity to meet a wonderful and extremely talented undergraduate student, Kevin Medina,” says Dr. Lafaille. “He came to our group with a solid background on immunology and B lymphocytes, the cells that make antibodies. His learning curve in the lab has been steep. He performed and analyzed experiments, discussed results, and presented them in a group meeting. And clearly, he is genuinely interested in the science behind it all, so we are so happy to see him motivated and inspired.”
  • What he learned: “I have come to appreciate how creative scientists can be. I realized how quickly scientists can produce new experiments and new ideas with little information given, and it is something I have come to appreciate.” – Kevin Medina

Student Chinonso (Chino) Nwakama left, in the lab with Brian Sweis, MD, PhD, and Jessica Ables, MD, PhD

Chinonso (Chino) Nwakama, University of Minnesota Twin Cities, aspires to be a physician-scientist

  • His Science Journey: “I was about 12 years old when my dad gave me Children’s Human Body Encyclopedia. When I stumbled on the “Nervous System” chapter I was taken by surprise. There were fascinating sections about the parts of the brain and the amazing capability of neurons. From that point on, I knew that learning more about the brain was in my future.

“My interest in substance use and addiction began in a high school club that I was involved in that focused on making our peers aware of the harmful effects of drugs and other substances.

“When I arrived on the University of Minnesota campus, I joined labs that introduced me to the world of drug-induced plasticity—specifically how sex differences can impact drug relapse and other related phenomena.

“My long-term goal is to pursue a career as a physician-scientist where I can use my knowledge of medicine at the individual level to guide research projects focused on gaining better understanding of how drug use affects the brain. I also want to inspire other future scientists who do not often see scientists who look like them.”

  • Where he worked: Lab of Jessica Ables, MD, PhD, Assistant Professor of Psychiatry, and Neuroscience, where he was also mentored by Brian Sweis, MD, PhD, Research Track Resident, Department of Psychiatry.
  • What he worked on: Investigating the effects of hyperglycemia on decision-making.
  • What he accomplished: “Chino worked diligently with us, studying how the ways in which the brain makes complex decisions is altered in metabolic disorders,” says Dr. Sweis. “He has been an exceptional student and has taken the lead on a project that has been a massive undertaking. He worked with a team of undergraduates, graduate students, postdocs, residents, and physicians, learning how to execute large-scale animal behavioral experiments, gaining critical skills in team and project management, and learning coding and data analysis techniques, all while being exposed to clinical patient populations in parallel with his ongoing efforts in basic and translational research.”
  • What he learned: “I’ve learned that there isn’t anything I can’t do. I’ve also learned how to problem solve and to not get flustered when things go wrong and not according to plan.”– Chino Nwakama

Three New Students at the Icahn School of Medicine Show the School’s Unique Partnership with the U.S. Military

The first year of medical school is probably one of the toughest challenges for any young person. For three incoming students at the Icahn School of Medicine at Mount Sinai, maybe not.

Three members of the United States military whose careers propelled them in different ways toward medicine have joined Icahn Mount Sinai through the school’s Institutional Partnership with the U.S. Military.

Through this unique pathway, the only one of its kind in the country, veterans gain an unprecedented opportunity to apply for admission to the School of Medicine without having to take the Medical College Admissions Test (MCAT). Also, candidates admitted into the program are offered provisional acceptance with the flexibility to defer their acceptance to continue their military service to meet all necessary requirements.

In interviews, the three talked about their experiences in the military, why they decided to attend medical school, and their plans for the future.

Katrina Nietsch

When Katrina Nietsch enrolled in the U.S. Naval Academy after graduating college, she knew she wanted to serve on the front lines.

She had been in middle school on September 11, 2001, and that was a major moment for her. “I wanted to serve my country from that moment on,” the former Lieutenant Commander says.

“The Navy underlined for me that the essence of mission success relies on the team, and caring for others.”

She signed up to be a pilot in the U.S. Navy and soon found herself flying the C-2A Greyhound, a twin-engine plane that delivers cargo to aircraft carriers.

Among many high stakes missions around the world, her first deployment as a C-2 pilot was a career turning point. She was on an aircraft carrier in the Pacific Ocean about 400 miles off the coast of Acapulco, Mexico, when a young sailor on board got very sick, suffering from severe seizures. She was tapped to fly the sailor to Mexico for life-saving care.

“Flying that MEDEVAC mission with our sailor on board was a watershed moment for me, as it galvanized my desire to pursue medicine,” she says.

She applied to Icahn Mount Sinai through the streamlined pathway to medical school for active service members. She was accepted in 2019 but the unique Military Institutional Partnership allowed the flexibility to defer acceptance for several years to fulfill her service commitment to the Navy.

“The flexibility of the program allowed me to continue my service as a pilot, which ultimately prepared me for medicine,” she says. “As in the Navy, medicine involves high-stakes responsibility and quick risk calculations under pressure. The Navy also underlined for me that the essence of mission success relies on the team, and caring for others.”

She played sports all her life, first as a young girl playing football with her older brother and was recruited to play varsity lacrosse at the Naval Academy. Now in medicine, she is leaning towards a career in sports medicine.

At the United States Military Academy at West Point Graduation in 2016, Tirone Young with with his stepfather James Imoh and his mother, Marie Imoh

Tirone Young

When Captain Tirone Young graduated from the United States Military Academy at West Point in 2016, he was commissioned as an infantry officer.

Due to injuries from an Army football career as a running back, he leveraged his background in nuclear engineering and transitioned to work as a nuclear medical scientist. While stationed in Landstuhl, Germany, he gained experience in health care and in public health. He also served as a subject matter expert on radioactive material and radiation-producing devices for United States and NATO Forces in Europe, Africa, and the Middle East.

“As members of our immediate environments and the larger country, we all stand to benefit if each person feels a responsibility to care for the people and resources around us.”

While working overseas, he noticed parallels between the values upheld in military service and those of a physician.

At the same time, he was processing some tough news in his family. “I lost my two biological grandmothers to cancer, he says. “With my mom being treated for breast cancer after successfully battling Hodgkin’s lymphoma, my interest in pursuing an oncology-related specialty within medicine was solidified.”

In 2020, he applied to Icahn Mount Sinai through its military institutional partnership program, and he was able to defer for a year while concluding his active-duty service abroad.

“My mother, father, and step-father honorably served in the military,” he says. “They introduced me to the concept of communal stewardship: As members of our immediate environments and the larger country, we all stand to benefit if each person feels a responsibility to care for the people and resources around us. Despite a dynamic change in careers, I continue to be guided by this foundational concept that my family embraced.”

Michael Auten

After graduating from West Point in 2016, Mike Auten traveled to Ukraine on a Fulbright fellowship focused on security studies. He then joined the Marine Corps as an officer, serving five “very fast-paced” years throughout the United States, Europe, and Africa. During his last tour of duty, while at a small base with a small emergency medical and trauma unit, he began to explore a career in medicine by shadowing the doctors and medics.

“This incredible team took care of the entire base, but they also treated the local security forces as well,” he says. “It was part of our mission and obligation to provide them with care, particularly if things went wrong.”

On witnessing emergency surgery on a remote military base: “It was a powerful introduction to the field of medicine and the rewards of helping and healing. That night completely changed my life.”

One night, a group of local security forces were traveling in a vehicle when they hit a roadside bomb.

“The whole medical team, from the front-line medics to the trauma surgeon, immediately sprang into action with a well-rehearsed plan,” he says. “When the patients arrived, they found that one had been badly hit in the calf, and I was able to observe an extremely intricate and challenging surgical procedure to repair a critical artery and save this patient’s life. The surgery endured for 12 hours, but afterward, I felt full of energy and clarity about what I wanted to do next. It was a powerful introduction to the field of medicine and the rewards of helping and healing. That night completely changed my life.”

A month later, he submitted his application to the Military Institutional Partnership Program at Icahn Mount Sinai.

“I wouldn’t be in medical school now if it wasn’t for the flexibility of the military pathway,” he says. “I am grateful for this program and for the very warm welcome we all received as veterans. We have experienced a huge feeling of belonging with fellow students and faculty and are thrilled to have the opportunity to go to medical school as part of this amazing community.”

In Donning New White Coats, Students Take on a New Chapter

The excitement in the Alice Tully Hall at the Lincoln Center for Performing Arts was palpable as families and friends waited for their loved ones to receive their coats in the White Coat Ceremony on Tuesday, September 13, as part of their journey at the Icahn School of Medicine at Mount Sinai. Meanwhile, outside the hall, medical student Mateo Restrepo was feeling nervous.

“It’s been challenging getting to this point,” he said, “but this is a moment me and all my classmates have been waiting for a long time.”

In his address, Dennis Charney, MD, Anne and Joel Ehrenkranz Dean of Icahn Mount Sinai, posed challenges to the 120 students who make up the class of 2026.

“But, now, as first-year students embarking on a career in medicine, the white coat you are about to receive represents a new tabula rasa,” Dr. Charney said. “How will you paint that blank canvas? What will you contribute to the field of medicine? How will you relieve suffering?”

Medical trainees then stepped up to the stage to receive their short white coats—a symbol of their journey to becoming fully fledged physicians with long white coats. As a faculty member robed each student, their stories about why they chose to enter health care were shown on a screen, spanning personal encounters with the health profession, heartfelt struggles with disease by family or themselves, and inspiration to challenge boundaries of health and science.

Meet: Mateo Restrepo, Class of 2026

Born in Colombia, Mr. Restrepo moved to Canada when he was five years old and was a professional soccer player. He then left his soccer career to pursue a medical education after graduating from the University of California, Santa Barbara.

What drew you to Icahn Mount Sinai?
Mount Sinai is uniquely situated to help underserved communities. Its presence in East Harlem especially means there are communities there that speak to my Latin [American] roots, and I look forward to seeing where I can help and learn from them.

What medical fields do you envision entering?
My sports background naturally makes me inclined toward orthopedic surgery, but I’m keeping an open mind.

What challenges might you anticipate in your medical journey?
One challenge that comes to mind is something I’ve already encountered: the need to take time to reconnect with myself during stressful times. I’ve learned more about myself during my time here and how I am able to deal with future challenges.

Meet: Katrina Nietsch, Class of 2026

Ms. Nietsch is one of three students who joined the Icahn School of Medicine at Mount Sinai through the school’s Institutional Partnership with the U.S. military. She was a pilot in the U.S. Navy and was accepted into the school in 2019.

What drew you to the Icahn School of Medicine at Mount Sinai?
I was drawn to the school’s commitment to underprivileged communities, which is second-to-none, and its commitment to veterans’ health. Just walking around campus and seeing the humility, expertise, and resourcefulness of the faculty and students is inspiring.

What medical fields do you envision entering?
I am thinking about a career in orthopedic surgery and sports medicine, but I am also looking at other possibilities, including women’s health.

What challenges might you anticipate in your medical journey?
I took the winding route since I served for 11 years in the military before finishing my commitment to the Navy and coming to medical school. It was time-consuming balancing a full-time career and preparing for medical school, so I am so grateful to be here now. As an older student, it has been a while since I was an undergraduate college-student, but I’m confident that with my intellectual curiosity and my military training, I will be able to tackle any challenges head on.

“Your white coats will never be cleaner or whiter than they are today,” remarked Victor Sta. Ana, MD, Director for Mount Sinai’s Primary Care Scholars Program, and Assistant Professor of Family Medicine and Community Health at Icahn Mount Sinai, in his keynote speech. He noted that the students’ journeys will only get more challenging. He described the isolation and grief he and his colleagues experienced during the height of the pandemic, and urged upon the incoming students a commitment to compassion and equity.

“I feel humbled and grateful for the opportunity to wear the white coat. I am also acutely aware of the responsibility which comes with wearing it,” said Katrina Nietsch. ”But I’m sure with the support of the faculty and my fellow peers, I’ll be up to the task to learn and find ways to get better as a provider.”

Here’s what some medical students had to say about what receiving their white coats meant to them:

Jennifer Chan, PhD, Receives Robin Chemers Neustein Postdoctoral Fellowship Award for Innovative Research

Jenneifer Chan, PhD, and Ian Maze, PhD

Jennifer Chan, PhD, whose work is vastly expanding knowledge about pregnancy, brain health, and stress, is the recipient of the 2022 Robin Chemers Neustein Postdoctoral Fellowship Award, established in 2010 to encourage and support female research scientists at the Icahn School of Medicine at Mount Sinai.

Recipients are senior postdoctoral scientists who intend to complete their training within two years, have demonstrated high-impact accomplishments in biomedical sciences, and exhibit the potential for an independent scientific career. Dr. Chan is the 23rd recipient of the award, created through a generous gift from Robin Chemers Neustein, JD, MBA, a former member of Mount Sinai’s Boards of Trustees.

Dr. Chan works in the laboratory of neurobiologist Ian S. Maze, PhD, in the Nash Family Department of Neuroscience. Dr. Maze, who was appointed as a Howard Hughes Medical Institute (HHMI) Investigator in 2021, is a Professor of Neuroscience, and Pharmacological Sciences, and the founding director of the Center for Neural Epigenome Engineering at Icahn Mount Sinai, the nation’s first center devoted exclusively to neuroepigenomic engineering.

Dr. Maze’s lab is focused on delineating the molecular and biochemical mechanisms of neuroepigenetic plasticity—changes in the underlying biochemical mechanisms that control whether genes are turned on or off within a given cell-type in the brain. This plasticity is important for allowing brain cells to appropriately respond to changing environments, which is critical for proper neurodevelopment—and which can cause disease when there is inappropriate tuning of gene expression.

Jennifer Chan, PhD

For example, aberrations in these processes can produce devastating neurological and psychiatric disorders, such as epilepsy, Parkinson’s disease, Alzheimer’s disease, substance use disorders, and major depressive disorders. These aberrations can occur during brain development or throughout life due to such factors as environmental toxins, physical trauma, chronic stress, and exposure to drugs of abuse.

The Maze lab—through the integration of technologically innovative and sophisticated new methodologies in chemical biology, proteomics, protein biochemistry/engineering, and structural biology—is advancing the understanding of these processes and working toward the development of targeted neurotherapeutics to treat these conditions.

“Using the most advanced epigenomic, metabolomic, and gene editing approaches in my lab, Dr. Chan is revolutionizing our understanding as to how environmental stimuli, both adaptive and maladaptive, impact epigenetic regulation of gene expression in the maternal brain to alter neural circuitry and behavior,” says Dr. Maze. “Delineating the mechanisms through which the experience of pregnancy imparts long-lasting changes in molecular and physiological properties of the brain promises to greatly aid in our understanding of how such a profound lifetime experience—shared by so many—contributes to brain health. Dr. Chan is an exceptionally talented and innovative young scientist, and I am absolutely thrilled by such prestigious recognition of her paradigm-shifting work.”

Dr. Chan joined the lab in 2018. Her research interests focus on understanding how biological systems outside the nervous system interact with stress to impact the brain during windows of neuroplasticity—times of active brain organization that are particularly susceptible to environmental and physiological challenges. Specifically, her work examines periods of early brain development and female reproductive experiences in rodents, including the long-term impact of pregnancy and postpartum experiences on the brain, and how stress disrupts normal organizational processes during these important windows.

“The experience of being pregnant dramatically changes both the body and brain,” says Dr. Chan. “While studies in patient populations and animal models have shown that these changes can persist long after giving birth, we still don’t understand the molecular mechanisms that control these processes.”

In particular, Dr. Chan investigates the contribution of epigenetic mechanisms underlying these experiences by combining molecular, biochemical, genome editing, and behavioral approaches in her postdoctoral research.

“The fundamental understanding of what reproductive experience does to the brain long-term has not been well studied,” says Dr. Chan. “My work shows that stress during these periods has a significant effect on the maternal rodent brain. I hope that through my research we can learn more about how pregnancy and postpartum experiences contribute to brain health and also emphasize that overall we need to do a better job of reducing stress during these critical windows—such as encouraging parental leave and making sure people have the financial, social, and health-related resources needed to support themselves.”

Says Dr. Chan: “I am incredibly honored to be the recipient of this year’s Robin Chemers Neustein Postdoctoral Fellowship Award. The direction for this research project was sparked by personal interest, and I am extremely encouraged by Dr. Maze’s support and that the selection committee also believes in these important questions.”
