Antony Rosen is the Mary Betty Stevens Professor of Medicine, and professor of pathology and cell biology. He is the director of the Division of Rheumatology and the vice dean for research at the Johns Hopkins University School of Medicine, as well as the director of inHealth, Johns Hopkins’ program in precision medicine and individualized health. Dr. Rosen received his medical degree from the University of Cape Town in South Africa in 1984. After completing his internship in medicine and surgery, he pursued postdoctoral studies in immunology at the Rockefeller University in New York (1987–1990). Drawn by a desire for a deeper understanding of human inflammatory diseases, he returned to clinical medicine and was an Osler resident and rheumatology fellow at The Johns Hopkins Hospital (1990–1994). He subsequently joined the faculty at Johns Hopkins in 1995, and rose to the rank of professor in 2002. He has been director of the Division of Rheumatology since then, overseeing a substantial expansion of the division. His research focuses on autoimmunity in the rheumatic diseases, using subgroups of patients with distinct phenotypes, trajectories and specific autoimmune responses to define molecular mechanisms.
