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.

In addition to Dr. Stout’s numerous research articles published in major medical and scientific peer-reviewed publications, she co-authors the Legionella chapter in Hospital Epidemiology and Infection Control, Harrison’s Principles of Internal Medicine, and the Manual of Clinical Microbiology.

Dr. Stout has authored more than 80 peer review papers on Legionella and Legionnaires' disease, which include papers in The New England Journal of Medicine, Journal of the American Medical Association, the Journal of Clinical Microbiology, the Journal of Infectious Diseases, and the Journal of the American Water Works Association.  Dr. Stout has also authored book chapters on Legionnaires' disease, including the Legionella chapter in the Manual of Clinical Microbiology

A national and international speaker, Dr. Stout has been invited to speak at the International Symposium on Legionella and the European Working Group on Legionnaires’ Disease. In addition, she regularly speaks at annual scientific and professional conferences for microbiology and infectious disease, the water treatment industry, and facilities management organizations. 

Dr. Stout is a member of the American Society for Microbiology, the Association for Professionals in Infection Control and Epidemiology, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), Association of Water Technologies (AWT), and the Cooling Technology Institute (CTI). She serves on Legionella standards and guidelines committees for both ASHRAE and CTI.
