David Katz, PhD, MPH

Acting Assistant Professor, Medicine, Division of Allergy and Infectious Diseases

Dr. David Katz, MPH, PhD, is an Acting Assistant Professor in the Department of Medicine at the University of Washington and an Epidemiologist for the HIV/STD Program of Public Health – Seattle & King County.  His research focuses on HIV self-testing, HIV/STD partner services, and mathematical modeling of HIV prevention strategies among MSM. He is currently the co-lead on two CDC-funded projects evaluating the integration of HIV prevention and care interventions into STD partner services, the PI of a study investigating the acceptability of conducting partner services via geosocial networking apps, and a Co-Investigator on an NIH-funded study to model the population-level effects of HIV self-testing strategies among MSM. He recently coordinated a randomized, controlled trial that demonstrated access to HIV self-testing at no cost increases testing frequency among MSM in Seattle. He received his MPH and Ph.D. in Epidemiology from the University of Washington.
