Dr. Sunil Chauhan is an immunologist and translational scientist whose research focuses on transplantation immunology, regenerative immunology, and immune regulation in tissue injury. His work has advanced the understanding of immune mechanisms governing inflammation, immune tolerance, fibrosis, and stem cell–mediated tissue regeneration. Dr. Chauhan has led multiple federally funded research programs supported by the NIH and the Department of Defense and has authored more than 120 peer-reviewed publications. He is internationally recognized for his contributions to immune modulation, ocular and tissue immunology, stem cell biology, and regenerative therapeutics, and has presented his work extensively at national and international scientific meetings. His research program bridges fundamental immunology and stem cell biology with translational approaches aimed at developing innovative therapies for transplantation, inflammatory, and degenerative diseases.

Dr. Sunil Chauhan’s research program focuses on the immunological mechanisms that regulate transplantation, inflammation, tissue repair, and regeneration. His laboratory investigates how innate and adaptive immune pathways influence graft survival, immune tolerance, fibrosis, and host defense, with particular emphasis on immune–stromal interactions, regulatory T cell biology, mast cell function, and the regenerative immunology of stem cells, including mesenchymal stem cells and induced pluripotent stem cells. A major focus of his work is the development of immunomodulatory and stem cell–based therapeutic strategies to enhance tissue regeneration and improve transplantation outcomes. His translational research integrates immunology, stem cell biology, and regenerative medicine to advance novel therapies for inflammatory, degenerative, and transplant-related diseases.
