Biography

The TOID Program’s Medical Director is Dr. Kieren Marr, Professor of Medicine and Oncology. Dr. Marr trained at Hahnemann University, Duke University and the University of Washington / Fred Hutchinson Cancer Research Center, where she was on faculty for 13 years prior to relocation to Johns Hopkins in 2008. Dr. Marr is a member of several national and international professional organizations, numerous national scientific steering committees, has authored over 150 peer-reviewed publications and textbook chapters, and edited two books in the area of infectious diseases involving immunosuppressed hosts. She is an elected member of the American Society for Clinical Investigators (ASCI) and is known worldwide for her translational and clinical research focused on diagnostics and treatment of invasive fungal infections. Her research has led to establishment of a JHU start-up company, MycoMed Technologies, focused on development of devices and drugs to enable strategies to prevent fungal infections in medically immunosuppressed people. She has an active academic interest in medical research innovation and commercialization and holds a co-appointment in the Carey School of Business. Dr. Marr sees patients and is active in clinical teaching as part of the Barker Firm faculty in the Department of Medicine, and the Transplant and Oncology Infectious Diseases inpatient and outpatient teams.
