DEEPAK A. RAO, MD, PHD
Assistant Professor of Medicine | Harvard Medical School
Division of Rheumatology, Inflammation, and Immunity
Co-Director, Human Immunology Center | Brigham and Women’s Hospital
Deepak’s research uses high dimensional analyses of patient samples, coupled with mechanistic studies, to define immunologic pathways that drive autoimmune diseases. He recently led a study published in Nature that discovered a unique T cell population called ‘peripheral helper T cells’ that promotes inflammation in rheumatoid arthritis. His efforts are directed at identifying immune cell pathways that can serve as biomarkers of treatment response or new therapeutic targets in rheumatic diseases.
