I will begin as an NSF Postdoctoral Fellow at the Courant Institute in September 2019. In August 2019, I completed my PhD in Applied Mathematics at Berkeley, where I was supported by an NSF Graduate Research Fellowship. My advisor at Berkeley was Lin Lin. Here is my CV (8/2019).
I work on analysis and numerics for electronic structure theory and quantum many-body physics. I am interested more broadly in applied analysis, statistical mechanics, and mathematical physics. To get a further sense of my interests, see what I read in graduate school. In particular, I have also done research in optimal transport, which was recognized recently with the SIAM Student Paper Prize. In 2018, my doctoral work was awarded the Bernard Friedman Memorial Prize in Applied Mathematics by the Berkeley math department.

Other research writings
Two views on optimal transport and its numerical solution (2015). My undergraduate thesis (supervised by Yanir Rubinstein and Rafe Mazzeo), which presented two new formulations of optimal transport problems leading to two corresponding methods for numerically solving them.
Asymptotics of Hermite polynomials (2015). A largely expository paper (for a course on orthogonal polynomials) about asymptotics of Hermite polynomials and the Gaussian Unitary Ensemble (GUE). Presents a result about the stationary states for the quantum harmonic oscillator, which, though likely nothing new, I think is fairly cool.
Spectral methods for neural computation (2013/14). A presentation for the Brains in Silicon lab outlining some ideas about how favorable Fourier-domain properties of certain neural tuning curves are naturally suited (in an idealized setting) for the computation of simple functions.
3D Shape Understanding Using Machine Learning (2013). A presentation about my work on using a deep learning framework to perform labeled segmentation of discrete surfaces and extract multiscale learned shape descriptors. To help with training, I introduced a new set of shape descriptors based on conformal maps.
(Note: This research was carried out during CURIS 2013 in Stanford's Geometric Computation Group.)
The k-discs algorithm and its kernelization (2012). Introduces and analyzes an extension of k-means allowing cluster centroids to be discs of arbitrary dimension, capable of recovering more diverse cluster geometries.
(Note: this research was carried out as a class project for CS 229 at Stanford.)
