Ellingson Lab


We study the epidemiology of infectious disease in healthcare and congregate living settings, antimicrobial resistance and stewardship, and occupational health. We ask applied research questions that address root causes and inform practical solutions. Our community partnerships, as well as national and international research collaborations, are critical to our multidisciplinary and community-engaged approach.

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 at the University of Arizona College 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 15 grants and contracts and has published over 50 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.
