About Me

I am a researcher at the Cornell Math+AI Lab. I graduated from the Division of Pure Mathematics at Cornell University in May 2026 with a Bachelor of Arts in Mathematics from the College of Arts and Sciences.

Current Focus

I am currently studying curvature pinching estimates for the Dirichlet energy of one-forms along Ricci flow on closed surfaces.
