Dr. Janet E. Stout, PhD

President and Director, Special Pathogens Laboratory

Dr. Janet E. Stout is president and director of Special Pathogens Laboratory, and research associate professor at the University of Pittsburgh Swanson School of Engineering in the Department of Civil and Environmental Engineering.

A clinical and environmental microbiologist, Dr. Stout is recognized worldwide for more than 30 years of pioneering research in Legionella. Her expertise includes disinfection and control strategies for the prevention of Legionnaires’ disease and other waterborne pathogens.

She is credited as the first to demonstrate the link between Legionnaires’ disease and the presence of Legionella in hospital water systems. Her seminal discovery in 1982, shifted the focus from cooling towers to water distributions systems as the primary source for Legionnaires’ disease. This changed the direction of research and expanded the water treatment industry’s approach to controlling Legionella. Since then, Dr. Stout has evaluated every major Legionella disinfection technology used today.

An advocate for prevention, Dr. Stout was instrumental in developing the first U.S. prevention strategy for hospital-acquired Legionnaires’ disease in 1993. Later adopted by the Veteran’s Health Administration and others, the guideline continues to serve as a national model for Legionella prevention.
