I am an Assistant Professor in the Department of Geography at the University of California Santa Barbara. I am also a research associate with the Broom Center for Demography.  I study and teach topics related to health geography, demography, and infectious disease epidemiology. 

I earned my Ph.D. in Demography from Princeton University in 2005 and my MPH in Epidemiology from the University of Washington in 2010. I joined UCSB in 2014. Previously I was an Assistant Professor in the Departments of Epidemiology and Global Health at the University of Washington, and a Postdoctoral Research Associate at the Center for Studies in Demography and Ecology at the University of Washington.  

The central focus of my research is on geographic mobility, sexual health, and HIV prevention.
