I am a dissertation-stage computer science Ph.D. student at the University of Iowa and a graduate research assistant at the Los Alamos National Laboratory. I am interested in applying techniques from computer science, geographic information systems (GIS), and mathematics to the field of epidemiology in order to simulate, analyze, and predict disease spread. In particular, my work focuses on disease spread across large geographic areas. I am also interesting in modeling human movement and activities.
