Nasia Safdar, MD Print Friendly Page

Faculty, University of Wisconsin School of Medicine and Public Health

Nasia Safdar has been the Medical Director of Infection Control at UW Hospital and Clinics since 2009. She came to Wisconsin in 1997 for her residency and fellowship. She is board certified in infectious disease and she focuses on healthcare-associated infections, particularly in the acute care setting. Dr. Safdar believes that many health care-associated infections can be prevented with adherence to known best practices. As medical director for the department of infection prevention, her job is to lead the department in its mission of reducing healthcare-associated infections by identifying, testing and implementing interventions that have benefit for reducing health care associated infections (HAI).


She is an associate professor of infectious diseases at the University of Wisconsin School of Medicine and Public Health and the Associate Chief of Staff for Research at the William S. Middleton VA Hospital. Her research includes the evaluation of novel and innovative strategies for prevention of HAI. She is currently leading the fecal bacteriotherapy program at UW Hospital and is the principal investigator of a current ongoing VA-funded trial of probiotics for reducing HAI.
