David DiTullio, MD (He/Him)

Executive Chief Resident, Inpatient, NYU Langone’s Tisch Hospital and Kimmel Pavilion

David grew up in Washington State and moved to Southern California for undergrad at Pomona College. He pursued his MD/PhD at UCLA (his PhD is in neuroscience and while the brain is cool, internal medicine is cooler). During grad school, he helped bolster the UCLA peer tutoring program and discovered a love of medical education.

David always knew he wanted to explore the East Coast. He was especially drawn to New York City and felt an immediate sense of community among the residents at NYU Grossman School of Medicine. The idea of working for our uniquely diverse care settings and learning about the complex systems of major healthcare institutions also helped solidify his choice. These characteristics have held true, and he cherishes opportunities to meet new friends in New York City.

In his role as chief resident, David is excited to build new teaching resources to help residents make the most of his favorite site. He looks forward to developing collaborative conferences with the faculty, teaching firm to help residents and hospitalists learn together, and do some teaching of his own.

David plans on making the most of New York City, including seeing more live theater, music, comedy, dance, and opera. He also plans to finish off his subway bucket list by taking the J, Z, and G lines, so he’ll be exploring more of Brooklyn along the way.


Abhinay Ramachandran, MD (He/Him)

Executive Chief Resident, Inpatient, NYC Health + Hospitals/Bellevue

Abhinay (Abhi) was born in West Bromwich, United Kingdom, and raised in Cleveland, Ohio. He went to the University of Pennsylvania for undergrad, majoring in bioengineering, and stayed there for medical school, where he pursued both an MD and an MS in translational research. His master’s thesis focused on the effects of increased afterload on hypertrophic cardiomyopathy using an in-vitro platform he helped develop.

Abhi came to NYU Grossman School of Medicine to train in a diverse clinical environment with a globally reaching population. He remains enamored with the unique opportunity to work at leading mission-driven hospitals like NYU Langone, Bellevue, and the VA NY Harbor Healthcare System. He has been part of the Tisch Hospital–Kimmel Pavilion track throughout residency, but is excited to serve as a Bellevue inpatient chief next academic year. He will be applying for fellowship in cardiology and plans to have an academic career that includes both research and medical education.

Outside of the hospital, Abhi loves anything related to sports. He enjoys playing tennis and exploring restaurants, bakeries, and coffee shops with his fiancé.


Kenneth Brill, MD (He/Him)

Chief Resident, Quality Improvement/Patient Safety, NYC Health + Hospitals/Bellevue

He was heavily involved in the premedical involvement community and the College Democrats, while pursuing research on the molecular evolution of yeast.

Ken attended NYU Grossman School of Medicine for his MD and stayed here for his residency. Through his education here, he developed a passion for serving the marginalized patient population of Bellevue and working to improve the quality of the care delivered to this underserved group. To him, there was no question that NYU Grossman School of Medicine was the place to be for his residency training. Not only has he been able to continue to serve the patients he loves, he has leveraged access to state-of-the-art care delivered at NYU Langone and been able to give back to our veterans at the VA NY Harbor Healthcare System primary care clinic. Ken appreciates the tight-knit community of residents at NYU Grossman School of Medicine and is grateful for the lifelong friends he made, while getting a world-class clinical education.

After working with the underserved and often undocumented patient population in Los Angeles, he wanted to build on this experience within a similar demographic in Sunset Park, New York, through pursing residency training at NYU Grossman School of Medicine. Throughout his chief resident year, Tyler wants to create a strong focus on procedural training and integrating point-of-care ultrasound (POCUS) into everyday learning. He plans on applying for gastroenterology fellowships this year and hopes to pursue the specialty as his primary focus.

He was drawn to residency at NYU Grossman School of Medicine and Bellevue because the program offered an opportunity to provide care to the large number of marginalized and underserved patients. Gustavo is thrilled to stay on as the Bellevue outpatient chief resident and plans to continue delivering passionate care that extends to social as well as medical needs. He also hopes to use this year to delve deeper into his role as an educator and leader, and ultimately continue a career in academic medicine.

Gaby (Gabrielle) Mayer, MD (She/Her)

Chief Resident, Primary Care, NYC Health + Hospitals/Bellevue

Gaby grew up in Caracas, Venezuela, before moving to New York City in elementary school. After her upbringing in the city, she studied art history at Amherst College. Though she fell in love with New England, she returned to the city to attend medical school at NYU Grossman School of Medicine. It was an easy decision, as the school offered her the opportunity to care for her home community of New Yorkers.

Medical school engendered a love of primary care—specifically queer primary care—which led her to stay here for residency in the primary care track. While in residency, Gaby has developed a deep interest in medical education and aspires to provide affirming care to queer folks, people living with HIV, and those who use substances. She is excited to serve as the primary care chief next academic year.

In her free time, Gaby loves to go for long walks throughout the city (especially when they end at a new restaurant with friends), distance running, calling her grandparents, and working on her culinary skills (she self-identifies as a Top Chef wannabe). She also has a podcast, Queer Health Pod, started with other members of the NYU Grossman School of Medicine community.

While at medical school, he co-founded a chapter of the Latino Medical Students Association and ran a community outreach program helping recently resettled refugees navigate the often-confusing healthcare system. He also volunteered as a scribe/interpreter to help conduct forensic medical and psychiatric evaluations for asylum seekers.

Given his strong interests in social justice, David was drawn to train at NYU Grossman School of Medicine for the opportunity to provide world-class care to the most marginalized populations regardless of their insurance or documentation status. During his training, he discovered a love of working with the critically ill, having complex goals of care discussions, and treating patients with pulmonary hypertension. David looks forward to continuing to help bolster the health equity curriculum and plans to pursue a pulmonary/critical care fellowship after his chief year.
