Dr. Andrew Mammen

Co-Director of the Johns Hopkins Myositis Center

Associate Professor of Neurology and Medicine

Dr. Mammen sees patients with diseases affecting muscle and has a special interest in autoimmune myositis and statin-associated myopathies.

His research focuses on statin-triggered muscle disease, muscle regeneration in myositis, as well as the link between myositis and cancer.

Dr. Mammen is the recipient of the 2007 Passano Physician Scientist Award and the 2012 Sir William Osler Young Investigator Award.
