About Me

My (official) name is Kaiwen Song . My preferred name is Kevin. Note that "Kaiwen" and "Kevin" are related.

I am a first year master student in mathematics at Universität Bonn, and I am mainly interested in algebraic topology and homotopy theory. From 2022 to 2025, I was an undergraduate student at the University of Cambridge. Sometimes I ask/answer questions on Math Stackexchange.
