Dr. Semir Beyaz is an Assistant Professor at Cold Spring Harbor Laboratory and Director of the Seckin Endometriosis Research Center for Women’s Health. He received his PhD in Immunology from Harvard University in 2017. His early work helped define epigenetic and nutrient-sensing pathways that control immune-cell lineage identity and intestinal stem cell function, linking aberrant regenerative fitness and impaired immune surveillance to cancer risk. The Beyaz laboratory now investigates how environmental inputs, including nutrients and the microbiome, reprogram the fitness of immune cells and epithelial stem cells through metabolic and epigenetic mechanisms to influence tissue regeneration, immune surveillance, and cancer. More recently, the lab has extended this framework to endometrium biology and endometriosis, examining how altered cellular fitness drives chronic inflammatory remodeling, with the goal of advancing improved diagnostics and disease-modifying therapies.
