I am Xi Liu, a PhD student in Geography and Social Data Analytics at Penn State. My advisor is Prof. Clio Andris, and I am part of the Friendly Cities Lab. I am also a graduate affiliate of GeoVISTA Center. Before coming to Penn State, I worked in Geosoft Lab with Prof. Yu Liu and received my Master’s degree from Peking University. I also hold a Bachelor’s degree in GIS from Tongji University with a minor in Economics from Fudan University.
In my studies, I explore data-driven models of human activities to understand cities and solve urban issues. My research interests include urban computing, social/spatial networks, place based data analytics, human mobility, and complexity in cities.
