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, gerontology, and cognitive decline. With an undergraduate degree in computer science and 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 over 550 peer-reviewed research articles, and is ranked #1 worldwide in organ transplantation expertise and influence by ExpertScape. Reflecting his contributions to health care, he was recently elected into the National Academy of Medicine. Reflecting the creativity and broad reach of his contributions, he received a prestigious Global Thinker Award from Foreign Policy Magazine and was named an Innovator of the Year by TIME Magazine. 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 several front-page features in the New York Times.
