Info

I'm a fifth year PhD student at UC Berkeley, currently (virtually) visiting Harvard University. I am applying for research postdocs this fall. My interests run towards cluster algebras, total positivity, and the structure of the totally nonnegative Grassmannian.

Talk Slides and Notes


Seminars

This semester I am organizing a reading group on Coxeter matroids, and co-organizing the Berkeley combinatorics seminar with Sylvie Corteel.

I co-organized the Talking About Combinatorial Objects Student Seminar (TACOS) with Mario Sanchez in Spring 2018 on Coxeter groups and related topics.
