Dorry Segev, MD, PhD, is the Marjory K. and Thomas Pozefsky Professor of Surgery and Epidemiology and Associate Vice Chair of Surgery at Johns Hopkins University. He is the founder and director of the Epidemiology Research Group in Organ Transplantation (ERGOT), the largest and most prolific group of its kind in the world. Dr. Segev was the first to demonstrate the survival benefit of incompatible kidney transplantation across the United States, and is responsible for the first HIV-to-HIV transplants in the United States. His NIH-funded research includes kidney exchange, desensitization, long-term donor risk, access to transplantation, expanding transplantation including HIV+ donors, geographic disparities, post-transplant outcomes, and the intersection between transplantation and gerontology. With a graduate degree in biostatistics, Dr. Segev focuses on novel statistical and mathematical methods for simulation of medical data, analysis of large healthcare datasets, and outcomes research. 

Dr. Segev has published nearly 500 peer-reviewed research articles, including 15 in JAMA, NEJM, and Lancet and over 150 in the American Journal of Transplantation. Reflecting this publication track record, he was recently awarded the American Society of Transplantation's Clinical Science Investigator Award. He is a current councilor of the American Society of Transplant Surgeons and former chair of the American Transplant Congress. His work has directly influenced policy, including two Congressional bills (the Norwood Act for kidney exchange and the HOPE Act for HIV-to-HIV transplants), and is regularly featured in widely read media including TIME magazine, Wall Street Journal, and the New York Times

Dr. Segev is most inspired by his role as a mentor, having mentored over 100 graduate students, residents, and faculty, and is the only general surgeon in the US funded by an NIH/NIDDK Mentoring Grant. more
