Bio

Catherine Karr MD PhD (she/her) is an environmental epidemiologist and pediatric environmental medicine specialist. She has a primary appointment in the University of Washington Department of Pediatrics, Joint in Environmental & Occupational Health Sciences, and Adjunct in Epidemiology. Her studies focus largely on low resourced communities in the U.S. as well as other low and middle income nations (Kenya). Her work represents methods comprising merging of large datasets on environmental factors and pediatric health outcomes as well as small in depth research using community engaged research practice. Indoor and outdoor air pollution, lead and pesticide exposures are focus areas of her expertise. She also maintains a general pediatric practice at the UW Pediatric Clinic at Roosevelt and directs a UW based regional outreach and consultation service, the NW Pediatric Environmental Health Specialty Unit (PEHSU).
