Ellingson Lab


We study infectious diseases in healthcare settings, households, and workplaces. Our current projects focus on antibiotic resistance in healthcare, household transmission of respiratory viruses, and the health of frontline workers including healthcare workers, first responders and farmworkers. We ask applied questions to 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 60 peer reviewed publications. At present, Kate has played an active role in the COVID-19 response, both on campus, with long-term care facilities throughout Arizona. She is also leading studies to understand SARS-CoV-2 infection risk among essential workers and within households.
