"Human mobility and HIV infection: What can we learn from network epidemiology?"
3:30 pm to 4:50 pm
Health Sciences K-069

Dr. Cassels



Dr. Susan L. Cassels
Assistant Professor of Epidemiology and Global Health

Dr. Susan Cassels, Ph.D., MPH, is an assistant professor of Epidemiology & Global Health at the University of Washington.  She received her PhD in demography from Princeton University in 2005 and an MPH in Epidemiology from the University of Washington in 2010 as a part of her postdoctoral training in the Center for Studies in Demography and Ecology and the Center for AIDS Research.

Dr. Cassels’ research interests are in the areas of demography and epidemiology, mathematical modeling, social network analysis, and infectious disease epidemiology, specifically HIV and other sexually transmitted diseases. She teaches an introductory course on epidemic modeling for infectious diseases in the department of Epidemiology. Currently, her research is focused on human mobility and its affects sexual network structure and HIV transmission in Ghana. 

While HIV occurs throughout the globe, the intensity of the epidemic varies substantially across populations and the determinants of the disparities in HIV prevalence and trends among populations remains an area of debate and intense scientific research. Recently, progress has been made in incorporating and understanding the importance of sexual networks, particularly partnership concurrency, as a key aspect of the transmission system and therefore an important target in HIV prevention. Thus far, work on sexual networks and HIV has largely ignored the question of migration, even though “periods of multiple partnerships”, an essential building block for concurrency, may be mediated by migration patterns. We will consider some of the methodological challenges of studying mobility, HIV, and sexual networks, and will present preliminary findings from Zimbabwe and Ghana.
