Kexing is a PhD student who joined our unit in September 2023. Kexing had previously studied at the University of Cambridge and graduated from Imperial College London (Ken Allen Prize, Dean’s List) after completing high school at Porsgrunn videregående skole in Norway. During his undergraduate studies, Kexing participated in the Lean project and formalized the Martingale Convergence Theorem. His work was mentioned in Kevin’s plenary ICM lecture about Lean and resulted in one publication.

A Formalization of Doob’s Martingale Convergence Theorems in mathlib, in Proceedings of the 12th ACM SIGPLAN International Conference on Certified Programs and Proofs.

Kexing also contributed to the Group Theory Game Project.
