I am a Benjamin Peirce Fellow at Harvard University. I work in low-dimensional topology; more specifically, I've been thinking about Lefschetz fibrations and mapping class groups of certain 4-manifolds.
I received my PhD in June 2025 from the University of Chicago, advised by Benson Farb. Before that, I was an undergraduate at Cornell University.
Here is my CV.
