David DiTullio, MD (He/Him)
Executive Chief Resident, Inpatient, NYU Langone’s Tisch Hospital and Kimmel Pavilion
David.Ditullio@NYULangone.org
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.

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.

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.
