I earned my PhD from Columbia in May 2025 under the supervision of Will Sawin. I will next be a postdoc at the University of New South Wales, working with Behrouz Taji.

My research lies in algebraic and arithmetic geometry. I am generally interested in using cohomological tools to study the nature of algebraic varieties. I am currently thinking about a relative version of the Du Bois complex and applications to Hodge theory. My papers are on arXiv.

Please contact me for a detailed research statement, teaching statement, or CV.
