About Me:

I am an analyst specializing in microlocal analysis and singular geometry and their applications to partial differential equations and mathematical physics more broadly. Previously, I did my PhD at MIT, where I was fortunate to be advised by Peter Hintz.


Ph.D. in Pure Mathematics, MIT, 2023.

B.Sc. in Mathematics and Physics, Stanford University, 2018.

Works in progress:

  • Full polyhomogeneity of the low-energy resolvent for short-range Schrödinger operators.
  • Microlocal analysis of the nonrelativistic limit of the Klein--Gordon equation. (Joint with Andrew Hassell, Qiuye Jia, Andras Vasy.)
Titles tentative. Click here for a live feed of me working on these manuscripts.

  • Stanford Math 21, Winter 2024: Calculus III
  • MIT 18.089, Summer 2021: Calculus for Naval Engineers.

Current topics of interest:

  • Wave propagation on manifolds, including both the Schrödinger equation and relativistic wave equations.
  • The construction of the BPZ minimal models of 2D CFT.
