Jikai Jin

Ph.D. student · Stanford university
I’m a third-year Ph.D. at Stanford ICME, advised by Prof. Vasilis Syrgkanis. Previously I studied computational mathematics at Peking University, advised by Prof. Liwei Wang.
I work on the frontier of intelligence, specifically on making data-driven algorithms more principled, more robust, and better adapted to societal considerations.
