I am an assistant professor at the University of Maryland at College Park.
Before joining the University of Maryland, I was an instructor of mathematics at Princeton University from 2018 to 2021, and an assistant professor of mathematics at Princeton University from 2021 to 2022. I completed my Ph.D. at Harvard University in 2018 advised by Clifford Taubes. Here is my CV.
My research interest is in gauge theory, Floer homology, and their interactions with geometric structures on 3 and 4-dimensional manifolds such as knots and links, foliations, contact structures, and symplectic structures.
