About Me
I am a GISer, GeoAI practitioner, Ph.D. student in Computer Science at the University of Minnesota, Twin Cities, advised by Prof. Yao-Yi Chiang. I am recently working on cartographical reasoning capability of Large Language Models and I am interested in Web-based Geographic Information System developing. In my spare time, I enjoy learning geography, philosophy, social science, playing music, and staying with my cat.
