Biography 

Susan Cassels, PhD, MPH is an associate professor of Geography and a research associate in the Broom Center for Demography at the University of California Santa Barbara. Her work spans many disciplines, including demography, epidemiology, and geography. Cassels’ research interests are in the areas of migration and health, epidemic modeling, HIV/AIDS, and sexual networks. Currently, the central focus of her research is on geographic mobility, sexual health, and HIV prevention. She studies social and behavioral determinants of HIV transmission dynamics – or in other words how and why certain people are more susceptible to HIV, and how, where and why HIV spreads to other people.

Dr. Cassels also uses mathematical models to explore the importance of social and behavioral determinants in HIV transmission dynamics. These models answer hypothetical “what if” questions to help policy makers decide how to implement HIV interventions. Dr. Cassels is currently collaborating with colleagues at the UW to identify how rapid home-use HIV testing strategies may impact HIV incidence in diverse populations of men who have sex with men.
