Dr. Baddley has an appointment at the Institute of Human Virology and the University of Maryland Stewart and Marlene Greenebaum Cancer Center (UMGCC). He recently joined our faculty in 2020, moving from the University of Alabama at Birmingham (UAB), where he was Professor of Medicine in the Division of Infectious Diseases.  After receiving an undergraduate degree from the University of North Carolina at Chapel Hill, Dr. Baddley earned his medical degree from Louisiana State University (LSU) School of Medicine, New Orleans. He completed an internship and residency at LSU Medical Center and fellowship in infectious diseases at University of Alabama at Birmingham, where he was Chief Infectious Diseases Fellow.  At UAB he served as Director, Transplant Infectious Diseases at UAB’s Comprehensive Transplant Institute and Director of the Infection Control Program at the Birmingham VA Medical Center.

Dr. Baddley’s clinical work focuses on prevention and management of infections in the immunocompromised host.  He participates in outpatient clinic and inpatient consult services for solid organ transplant and cancer patients.   Dr. Baddley has a part-time position at the Baltimore VA Hospital, where he is involved with Antimicrobial Stewardship and clinical work at the Infectious Diseases clinic.

Dr. Baddley’s research interests include clinical trials and outcomes research related to immunocompromised hosts.  Ongoing areas of research include clinical trials of novel antifungal and CMV therapies, epidemiology of fungal infections, HIV transplantation and risk of infection and outcomes with use of biological therapies/immunomodulators. 

Dr. Baddley currently serves as an Associate Editor of Open Forum Infectious Diseases and is on the ABIM’s Infectious Disease Exam Committee. He serves as co-chair of the education committee of the Mycoses Study Group Education and Research Consortium and as Secretary/Treasurer of the Transplant Infectious Diseases group of the Transplantation Society. He recently served as Chair, WHO Histoplasmosis Guidelines Development Group.
