My name is Qingyuan Bai (白庆源). My friends mostly refer to me as `Bai. Preferred pronouns: he/him.

On this page you can find records of my mathematics-related activities.

I was a PhD student in Mathematics at Københavns Universitet, a master student at Peking University, and an undergraduate student at Sichuan University.
