I am an Assistant Professor of Instruction in the Department of Mathematics at Texas State University, beginning in Fall 2026.  I work in differential geometry and mathematical general relativity, with current interests in geometric analysis, information geometry, and probabilistic approaches to geometric problems.

Much of my work concerns how global geometric structure is detected by analytic quantities — mass, entropy, and rigidity. My current projects extend those tools toward stochastic dynamics and spaces of probability measures.

Previously I was a Harry Bateman Postdoctoral Scholar Teaching Fellow at Caltech (2022–2025), mentored by Antoine Song, and a Fuqua Research Assistant Professor at the University of Miami (2020–2022), mentored by Gregory Galloway and Pengzi Miao. I received my Ph.D. from the University of Connecticut in 2020 under Lan-Hsuan Huang, and my B.Sc. and M.Sc. from Sogang University.
