Associate Director, Johns Hopkins Myositis Center
Investigator, National Institutes of Health
After obtaining his M.D. and Ph.D. at Johns Hopkins, Dr. Mammen completed his neurology residency and neuromuscular fellowship at the same institution. He co-founded the Johns Hopkins Myositis Center in 2007, where he and his colleagues discovered a novel form of autoimmune myopathy associated with statin use and autoantibodies recognizing HMG-CoA reductase, the pharmacologic target of statins. In 2014, Dr. Mammen moved to the NIH, where he is an Investigator and Leader of the Muscle Disease Unit. His laboratory focusses on understanding the pathological mechanisms underlying disease in dermatomyositis, polymyositis, immune-mediated necrotizing myopathy, and inclusion body myositis. In addition to seeing myositis patients at the NIH Clinical Center, he maintains an appointment as Adjunct Professor of Neurology and Medicine at Hopkins, where he continues to see patients at the Myositis Center.
