Ellingson Lab


We study infectious disease transmission and prevention in healthcare settings, antimicrobial resistance, and occupational health. With funding from international, federal, state, and local agencies, we approach our work through health equity and One Health lenses with multidisciplinary collaborations on campus, with rural and border communities, and with national and international partners.

About the PI

Katherine (Kate) Ellingson began her postdoctoral career in public service – first as an Epidemic Intelligence Service officer and Health Scientist at the Centers for Disease Control and Prevention, and then as a Senior Epidemiologist at the Oregon Health Authority – where she focused on patient safety, occupational safety, infection prevention, antibiotic resistance, and outbreak response (e.g., H1N1, Ebola and Zika). In 2017, Kate joined the Department of Epidemiology and Biostatistics Department at the University of Arizona presentCollege of Public Health. 

Since joining the University of Arizona, Kate has  mentored post-docs, graduate students, and undergraduates. She has served as a Principal Investigator or co-investigator on more than 10 grants and contracts and has published over 40 peer reviewed publications. At present, Kate plays an active role in the COVID-19 response, both on campus and with long-term care facilities in Pima County. She is also leading studies to understand SARS-CoV-2 infection risk among healthcare personnel, first responders, and other essential workers.
