Ellen Gravallese, M.D.
Division Chief  
Professor of Medicine & Cell Biology

Dr. Gravallese’s research in the laboratory has focused on pathogenic mechanisms of inflammatory arthritis, with a special interest in rheumatoid arthritis. Contributions include the identification of cell types producing matrix metalloproteinase enzymes that destroy the extracellular matrix of cartilage in disease such as rheumatoid arthritis and pigmented villonodular synovitis, and the identification of pathways leading to bone destruction in rheumatoid arthritis. Clinical research interests have focused on focal bone erosions in rheumatoid arthritis and the relationship of articular and systemic bone loss. Dr. Gravallese’s clinical interests include rheumatoid arthritis and osteoporosis.

Ann Marshak-Rothstein, Ph.D.
Professor of Medicine
Interests: Systemic autoimmune diseases including systemic lupus erythematosus and scleroderma.
Research: The main focus of the Marshak-Rothstein lab is to understand how components of the innate immune system contribute to the onset and development of systemic autoimmune diseases. In particular, the goal is to understand to contribution of toll-like receptors 7 and 9 in the activation of autoreactive B cells. In addition, the lab is exploring the proinflammatory and proapoptotic role of Fas ligand in models of fibrosis and immune privilege.
