Louis Xiang Li

Ph.D. Student in Philosophy ยท Fudan University

I am a Ph.D. student in Philosophy at Fudan University under the supervision of Prof. Will Johnson. My research interests lie in model theory and its applications, particularly at the interface between model theory and algebra.

I received two M.S. degrees, one in Mathematics and one in Computer Science and Engineering, from The Ohio State University in 2025. My M.S. advisors in Mathematics were Gabriel Conant and Ivo Herzog, and my M.S. advisor in Computer Science and Engineering was Zeyu Guo. Prior to that, I earned my B.S. in Computer Science and Engineering from The Ohio State University in 2022.

I was a member of the OSU CSE mental wellness committee. R.I.P. CSE mental wellness committee, long live SSAFE committee.
