Alison Hill

Prof. Hill’s research group develops mathematical models of infectious disease dynamics and evolution within patients and across populations, with the goal of guiding intervention strategies. She has worked extensively on HIV/AIDS, focusing on the evolution of drug resistance, the dynamics of latent infection, and the impact of novel immunotherapies.

Since 2020, she has been involved in modeling efforts to guide public health responses to COVID-19/SARS-CoV-2 and other respiratory infections, working with the Johns Hopkins Infectious Disease Dynamics group and the Scenario Modeling Hub. Other work has included RSV, KSHV, antimicrobial resistance, bed bug infestations, and the opioid crisis. More generally, Prof. Hill is interested in the evolutionary theory of infectious diseases, the role of population structure in disease spread and evolution, and the intersection of human behavior with disease spread and control. She has taught infectious disease modeling at the undergraduate, graduate, and continuing-professional-education levels. Prof. Hill received her BS from Queen’s University, her PhD from the Harvard-MIT Division of Health Sciences & Technology, and her MPH from Harvard School of Public Health. She received an NIH Director’s Early Independence Award, and was faculty at Johns Hopkins University before moving to University of Toronto in 2025.
