2025-2026 Chief Residents
Chief residents are selected in their final year of residency and typically complete one year of fellowship before returning to start their chief resident year. In 2024-25, the Department of Medicine expanded the chief resident cohort to have four clinical chief residents, in addition to the VA Chief Resident for Quality and Safety.

Chief residents support the residents and the program, including serving as teaching attendings at Duke University Hospital, the Durham VA Medical Center, Duke Regional Hospital and the Duke Outpatient Clinic. Additionally, chief residents are a key part of the medicine residency team, providing invaluable leadership, teaching and support for trainees. The incoming chiefs join a strong tradition of resident leadership, and we look forward to their contributions to the Department of Medicine.
