Han GAO

Welcome to my homepage!

I am a postdoctoral researcher in the LogICS group at Institute of Computer Science of the Czech Academy of Sciences. I work on structural proof theory for non-classical logics.

Prior to the current position, I completed my Ph.D. in October 2025 under the supervision of Prof. Nicola Olivetti at Laboratoire d'Informatique et Systèmes (LIS), affiliated with Aix-Marseille Université and CNRS. In my thesis, I conducted proof-theoretic studies of (intuitionistic) modal logics. Before starting my Ph.D., I received my Master's degree at Tsinghua University (Beijing, China) in 2022 and Bachelor's degree at Lanzhou University (Lanzhou, China) in 2019.

My complete résumé is available upon request.
