Hi, this is Canyu Chen (陈灿宇). I am a CS Ph.D. student at Northwestern University and a member of the Northwestern MLL Lab, fortunately advised by Prof. Manling Li. I received my B.S. from the University of Chinese Academy of Sciences (UCAS). I have the privilege of collaborating with Prof. Dawn Song, Prof. James Evans, and Prof. Philip Torr. I am grateful for the previous mentorship from Prof. Kai Shu.

I focus on Truthful, Safe and Responsible (Multimodal) LLMs and Foundation Agents 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 knowledge 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. Feel free to contact me via wechat ID : alexccychen or email canyuchen AT u.northwestern.edu
