About Me

My (official) name is Kaiwen Song. I am a second year master's 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.

You may often see my name written as Kevin. This is my preferred name in the context of English. Note that "Kaiwen" and "Kevin" are related.
