About Me

My name is Kai Sun. I am a postdoctoral associate in the Department of Geography at the University at Buffalo (UB), advised by Dr. Yingjie Hu. My current major research interest is in geospatial artificial intelligence (GeoAI), with a special focus on understanding and extracting location descriptions from disaster related social media messages. CV can be downlaoded here.
