Rate My Professor Lindsay Keegan

Lindsay T. Keegan is a Research Associate Professor in the Division of Epidemiology, Department of Internal Medicine at the University of Utah's Spencer Fox Eccles School of Medicine. She holds adjunct appointments in the Departments of Family and Preventive Medicine and Population Health Sciences. Keegan earned a BS in Mathematics from the University of Florida in 2010, a PhD in Biology from McMaster University in 2015—where her dissertation was titled 'Malaria Control: Insights from Mathematical Models' under supervisor Jonathan Dushoff—and completed a postdoctoral fellowship at the Johns Hopkins Bloomberg School of Public Health from 2015 to 2019. She joined the University of Utah in 2019 as a Research Assistant Professor and leads the Utah Infectious Disease Dynamics Group.

Keegan's research centers on infectious disease transmission dynamics, developing and applying statistical and dynamical methods to understand the ecology and evolution of pathogens, particularly in healthcare settings and for emerging diseases. Her work addresses outbreak modeling and interventions for pathogens including COVID-19, Clostridioides difficile, Zika, diphtheria, and cholera. Key publications include 'Environmental and Health Care Personnel Sampling and Detection of Clostridioides difficile on High-Touch Hospital Surfaces' (JAMA Network Open, 2025), 'The Effectiveness of Face Mask Mandates on COVID-19 Transmission in Utah Counties' (Public Health Reports, 2024), 'Evaluation of Individual and Ensemble Probabilistic Forecasts of COVID-19 Mortality in the United States' (Proceedings of the National Academy of Sciences, 2022), and research on broader antibiotic use altering cholera outbreak courses (2025). With over 1,450 citations on Google Scholar, her contributions have informed public health decision-making, including model-based support for COVID-19 responses in Utah. She has delivered seminars such as 'Model-Based Decision Support for COVID-19 in Utah' and 'Coronavirus Chat,' and mentors undergraduate researchers through the Office of Undergraduate Research.
