I'm an Assistant Professor in the Mathematics Department at
Northwestern University. I was previously a Ritt Assistant Professor
at Columbia, and before that I received my PhD from UC Berkeley, where my advisor was Nicolai Reshetikhin.
Here is a copy of my CV.

My email address is
My office is 225 Lunt Hall.
I work on problems involving quantum groups, higher Teichmuller theory,
cluster algebras and integrable systems.
Here are some links to my papers on the arXiv:
Quantum decorated character stacks (joint with David Jordan, Ian Le and Alexander Shapiro.)
K-theoretic Coulomb branches of quiver gauge theories and cluster varieties (joint with Alexander Shapiro.)
Superintegrability of generalized Toda models on symmetric spaces (joint with Nicolai Reshetikhin.)
On b-Whittaker functions (joint with Alexander Shapiro.)
categories from quantum groups I: algebraic aspects (joint with Alexander Shapiro.)
A cluster realization of the R-matrix from
quantum character varieties (joint with Alexander Shapiro.)
Quantum groups, quantum tori, and the Grothendieck-Springer resolution (joint with Alexander Shapiro.)
Dual pairs of quantum moment maps and doubles of Hopf algebras (joint with Alexander Shapiro.)
Algebraic integrability of the classical XXZ spin chain with reflecting boundary conditions
Integrable systems from the classical reflection equation
The Universal Kummer Threefold (joint with Qingchun Ren, Steven Sam and Bernd Sturmfels.)
XXZ Scalar Products, Miwa Variables and Discrete KP (joint with Omar Foda.)
Here are the slides from some talks I have given:

positivity and continuous tensor categories, ZMP Colloquium,
November 16 2017.

In Fall 2013 at Berkeley, Alexander Shapiro and I co-organized a seminar on
integrable systems. Here is a link to the seminar website, where you

Slides for the accompanying talk
undergrad thesis "Classical integrable systems and linear flows on
tori", written under the supervision of Omar Foda.
An article by Jerry Koliha, Sam Chow and me in the AustMS Gazette on some weird (?) facts about the Lebesgue measure of the boundary of a set.
