Hi, this is Canyu Chen (陈灿宇), a Computer Science Ph.D. student at Illinois Institute of Technology (IIT) since Fall 2021. Before joining IIT, I received my B.S. in Computer Science from the University of Chinese Academy of Sciences (UCAS) in 2020. I am actively looking for a new Ph.D. position starting from Fall 2025 because my previous advisor has moved to another university. Please feel free to contact me if you are interested in my research. (email: cchen151 AT hawk.iit.edu or wechat ID: alexccychen)

I focus on Truthful, Safe and Responsible Large Language Models with the applications in Social Computing and Healthcare. I have started and led the LLMs Meet Misinformation initiative, aiming to combat misinformation in the age of LLMs. I co-led the Editing LLMs initiative, aiming to explore and understand knolwedge editing in LLMs. I am also one organizer of the OracleLLM community, dedicated to exploring and advancing the concept of LLMs-as-Oracles. I aim to pursue Safe and Aligned Artificial General Intelligence in the long run. I am always happy to chat and discuss potential collaborations, or give talks about my research in related seminars.
