Mark Sulkowski, M.D., has been appointed director of the Department of Medicine for Johns Hopkins Bayview Medical Center, effective July 1, 2026. This position was formerly held by Samuel Durso, M.D., M.B.A., who recently assumed the role of director for clinical bedside skills at Bayview. A distinguished clinician-scientist and accomplished academic leader, Sulkowski brings more than two decades of experience at the Johns Hopkins University School of Medicine to his new role and a deep commitment to the Johns Hopkins Bayview community.

Since 2019, Sulkowski has served as director of the Division of Infectious Diseases at the medical center, and he has served as associate dean for research in the National Capital Region, where he has led research at Johns Hopkins Howard County Medical Center, Suburban Hospital and Sibley Memorial Hospital since 2018. In these roles, he has demonstrated exceptional leadership in advancing clinical care, research and education. As director of the Division of Infectious Diseases at Johns Hopkins Bayview, he has successfully expanded clinical services, strengthened inpatient and outpatient programs, and led key initiatives including antimicrobial stewardship, infection control and the growth of the Outpatient Parenteral Antimicrobial Therapy (OPAT) program — improving care delivery while reducing length of hospital stay and readmissions. Sulkowski will step down as division director and associate dean to fill his new role.

At the school of medicine, Sulkowski has led major efforts to enhance clinical research infrastructure, supporting thousands of faculty and accelerating the translation of scientific discovery into clinical practice. His leadership during the COVID-19 pandemic was instrumental in establishing systemwide clinical research programs and advancing novel diagnostics and therapeutics. He will continue to serve school of medicine faculty members as senior associate dean for clinical trials and director of the Office of Clinical Trials.

Nationally recognized in infectious diseases, Sulkowski has led groundbreaking work in viral hepatitis, including efforts that dramatically reduced hepatitis C burden among patients in the Johns Hopkins HIV clinic and that expanded access to curative therapies for vulnerable populations. His work reflects a strong commitment to health equity, community engagement and improving outcomes for underserved patients.

As director of the Department of Medicine at Johns Hopkins Bayview, Sulkowski is committed to fostering a collaborative, inclusive environment that supports faculty, trainees and staff while advancing the medical center’s tripartite mission of clinical care, research and education. His vision emphasizes program growth, interdisciplinary collaboration and continued investment in innovation and discovery.

Please congratulate Mark Sulkowski on his appointment to this important leadership role.
