Jialin Lu
I am Jialin (Mike) Lu, a Computer Science Ph.D. student at Simon Fraser University, advised by Wuyang Chen.
Previously, I completed my undergraduate studies at the University of British Columbia.
My research focuses on AI for Mathematics and formal reasoning. I am interested in making AI reasoning verifiable and trustworthy through formal languages such as Lean, and building agentic systems that accelerate mathematical research.
