The strong connections she has formed with colleagues and mentors enhance her day-to-day experience, with every familiar face on the mega block serving as a warm reminder of the supportive community around her. As the Tisch-Kimmel inpatient chief, Sharn is eager to create a stimulating and enjoyable environment for her residents, drawing from her own positive experiences during training. She will be applying for a cardiology fellowship this year, with the aim of pursuing a career in academia.

Outside the hospital, Sharn immerses herself in the vibrant NYC life while staying close to her family.

Jacky is thrilled to serve as Bellevue inpatient chief during this academic year and build her teaching, mentoring, and leadership skills. After her chief year, Jacky plans to pursue fellowship in hematology/oncology.

Outside of the hospital, Jacky enjoys exploring new neighborhoods and restaurants with her friends and family, Peloton rides, listening to podcasts, and watching Broadway shows with her husband, Hammad, a current NYU neurosurgery resident with whom Jacky feels lucky to have matched together to NYU for residency!

Katie Havranek, MD, MPH (She/Her)

Primary Care Chief Resident, Internal Medicine, NYC Health + Hospitals/Bellevue
Kathryn.Havranek@NYULangone.org

Katie grew up in Denver, Colorado. She received her bachelor’s in international studies from Macalester College. She moved to Washington D.C. to pursue her interest in global health policy but found herself more interested in becoming a doctor than in crafting policy. She received a pre-medical post-baccalaureate certificate from the University of Vermont. She studied medicine at the University of Colorado where she pursued her interests in care for patients experiencing homelessness and immigrant health. She received her master of public health from the Colorado School of Public Health in epidemiology.

Katie was drawn immediately to NYU during her interview day for its opportunity to train in three unique hospital systems, the culture of trust between residents and faculty, and the opportunity to serve the NYC community in the inpatient and outpatient setting. She has loved her time in the Primary Care track as she was also able to grow a panel of patients at Gouverneur while also exploring her interest in endocrinology. She plans to pursue endocrinology fellowship next year.

Katie loves New York City where she has become both a bagel and a pizza expert. She loves live theater, free activities at Bryant Park, the Comedy Cellar, and Carnegie Hall. She is excited to continue her exploration of the city this year.

Sharon Klein, MD (She/Her)

Chief Resident, Quality Improvement & Patient Safety, VA Medical Center
Sharon.Klein@NYULangone.org

Sharon was born in Brooklyn, New York, and was raised in New Jersey. She went to Vanderbilt University for her undergraduate degree where she studied economics before going on to medical school at the Zucker School of Medicine in Long Island. She chose NYU Langone as a residency for its collegial culture and opportunity to serve such a varied patient population across all three sites. The clinical experiences in residency across a private, public safety-net, and VA hospital have shaped Sharon’s research in studying the role healthcare systems play in influencing health outcomes. Sharon hopes to continue this research as a cardiology fellow and ultimately pursue a career as an academic clinician, researcher, and educator.

Outside of medicine, Sharon enjoys rock climbing, skiing, road cycling, and cooking with friends and family. She’s also on a mission to prove that rock climbing is the best way to spend a Saturday—despite her friends’ insistence that brunch might be less hazardous.

Amber Whitley, MD (She/Her)

Chief Resident, Inpatient, NYC Health + Hospitals/Bellevue
Amber.Whitley@NYULangone.org

Amber was born in Manhattan, New York, but grew up in Morristown, New Jersey. She attended North Carolina State University for college and graduated with a bachelor of arts in psychology and a bachelor's of science in biology. She attended the Brody School of Medicine at East Carolina University for medical school, where she enjoyed tutoring her fellow medical students with the hope of helping them achieve their academic goals.

Amber always knew she wanted to come back home and live in the robust city of New York. She came to NYU Grossman School of Medicine because she wanted to serve patients from communities with limited access to care, and loved that Bellevue provided excellent care to all patients regardless of the patient's income or insurance status. She also was drawn to the supportive, family environment created by the residents and faculty and the opportunity to train in the unique three hospital system.

In her role as chief resident, Amber is excited to advocate and support residents. She is also excited to teach learners at different levels and will ultimately continue a career in academic medicine as a hospitalist next year.

In her free time, Amber enjoys eating at new restaurants, her morning Pilates sessions, and going to Broadway shows. She is currently training for a half-marathon, so you can find her running in Central Park or along the East River on the weekend.

Terry Li, MD (She/Her)

Chief Resident, Inpatient, NYC Health + Hospitals/Bellevue
Terry.Li2@NYULangone.org

Terry was born at NYU but grew up in New Jersey. She attended college at Cornell University, where she majored in biology and nutrition, and minored in health policy. She was involved in global health research in the Department of Nutrition and volunteered in the Ithaca community with the local 4H and free clinic. It was during this time that she developed a keen interest in public and population health and caring for communities with limited access to healthcare.

After a gap year working as a medical scribe in an emergency department, she attended NYU Grossman School of Medicine for her MD. She developed a passion for internal medicine early on, applying to the 3-year program after her first year of medical school to fast track into internal medicine residency at NYU. For her, staying at NYU for residency training was one of the best decisions because she was able to learn and grow amongst friends, taking care of a complex and varied patient base across three unique hospital systems and in one of the most exciting and dynamic cities in the world. She found incredible mentors in gastroenterology that allowed her to expand her clinical interests and knowledge while working on projects related to population health and healthcare quality.

Outside of medicine, Terry loves to stay active, whether that is heading to a volleyball game, jogging outside, or going to a fitness class with friends. She keeps a long running list of which restaurants she wants to try next and is always planning her next vacation.

The NYU community has deepened her respect for the diverse pathophysiology of diseases and enriched her professional and personal growth.

As a chief resident, Jahnavi is enthusiastic about leading the new Academic Half Day curriculum series under the guidance of Brooklyn program leadership. She is eager to develop interactive case conferences with faculty and staff, foster residents' teaching skills through Morbidity and Mortality presentations, and mentor colleagues in achieving their career aspirations.
