I am Rongxiang Su, a second-year Ph.D. student at the "intersection" of GeoTrans Laboratory and MOVE lab of the Department of Geography, University of California Santa Barbara, advised by Dr. Konstadinos Goulias and Dr. Somayeh Dodge. In GeoTrans, my research is focused on understanding human mobility patterns and travel behavior using spatio-temporal analytics, statistical approaches, discrete choice models, and machine learning techniques. In MOVE, I am developing time geography-based contact tracing techniques and investigating human interaction patterns in space and time using big GPS tracking data.
