About

I am an Associate Professor in the Department of Mathematics at Cornell University. My research sits broadly in numerical analysis, scientific computing, computational physics, and the theoretical aspects of deep learning.

My current work focuses on spectral methods, low-rank approximation, operator learning, the mathematics of deep learning, and dynamical systems. I am especially interested in problems where rigorous mathematics and effective algorithms sharpen one another.

Background

I received a DPhil in Numerical Analysis from the University of Oxford in July 2014, where I was supervised by Lloyd N. Trefethen. My thesis was titled Computing with functions in two dimensions. Before joining Cornell, I was an Applied Math Instructor at MIT from 2014 to 2016.

At Cornell

I joined Cornell as an Assistant Professor in July 2016 and became an Associate Professor in February 2022. I work with students and collaborators across applied mathematics, scientific computing, machine learning, and related areas.

Selected activities

I co-organize Cornell’s undergraduate math modeling competition, helped lead an Engaged Cornell curriculum grant, and co-organized the online e-NLA seminar and CMC seminar.

I have also served as a mathematics consultant for the PBS Infinite Series episodes “Why Computers are Bad at Algebra” and “How to Generate Pseudorandom Numbers”.
