I am an NSF Graduate Research Fellow and fifth year math PhD student at UC San Diego. I expect to graduate in June 2022.
My adviser is Jacques Verstraëte.
My CV can be found here.

My research interests are in combinatorics, and I am particularly interested in graph theory, extremal combinatorics, and probabilistic combinatorics.
Many of the problems I work on involve extremal properties of F-free hypergraphs and of random objects such as random graphs and permutations; but I am happy to work on any problem as long as it's interesting or fun!

Selected publications:

- Counting Hypergraphs with Large Girth (with Jacques Verstraëte). Submitted, 2020.
- Relative Turan Problems for Uniform Hypergraphs (with Jacques Verstraëte). SIAM Journal of Discrete Mathematics (Accepted), 2020.
- Card Guessing with Partial Feedback (with Persi Diaconis, Ron Graham, and Xiaoyu He). Combinatorics, Probability, and Computing, 2020.
- Slow Recurrences. Journal of Number Theory, 2019

- I'm on the organizing committee for the Graduate Student Combinatorics Conference 2022. The conference will be held March 25-27, 2022 at UCSD.
- With Jason O'Neill I co-organize ABACUS, the Graduate Student Combinatorics Seminar at UCSD.
- With Vaki Nikitopoulos I co-organize Food for Thought, the Graduate Student Seminar at UCSD.
