I am a limited-term assistant professor at UGA. I recieved my Ph.D. from UC Davis in 2026, where I was co-advised by Eugene Gorsky and Melissa Zhang.
I study low-dimensional topology and link homology theories. More specifically, I am interested in manifolds up to dimension 5 (mostly exotic phenomena in dimension 4), quantum/Floer theoretic link homology theories, categorification, and how these topics coalesce.
