Bio

Hi, this is Canyu Chen (陈灿宇). I am currently a third-year Ph.D. student in the Department of Computer Science at Illinois Institute of Technology (IIT) since Fall 2021, advised by Prof. Kai Shu. Before joining IIT, I received my B.S. in Computer Science from the University of Chinese Academy of Sciences (UCAS) in 2020.

My research interests focus on Safe and Responsible Large Language Models with the applications in Social Computing and Healthcare. Happy to chat and discuss collaborations. Feel free to contact me via Email (cchen151 AT hawk.iit.edu) or WeChat (ID: alexccychen).
