Sang Kim, MD, PhD

Dr. Sang Kim is an early-stage investigator and physician-scientist at Yale School of Medicine focused on immune checkpoint receptors on T cells in both normal physiology and autoimmunity. During his rheumatology fellowship at Yale, he earned a PhD in Immunobiology, where his dissertation research identified a novel CD4+ T cell subset in human tonsils that supports memory B cell antibody production. This work was published in the Journal of Immunology and contributes to our understanding of human T cell–B cell interactions. Dr. Kim’s research aims to uncover the mechanisms of immune regulation in autoimmune disease, using translational approaches to link clinical observations to basic immunology. His long-term goal is to develop targeted therapies that modulate immune checkpoints to restore immune balance in patients with rheumatologic conditions.
