I am an NSF Graduate Research Fellow and second year math PhD student at UC San Diego.
My research interests are in combinatorics, and I am particularly interested in graph theory, extremal combinatorics, and enumerative combinatorics.
My advisers are Fan Chung-Graham and Jacques Verstraete.
My CV can be found here.

With Jason O'Neill I co-organize the Graduate Student Combinatorics Seminar at UCSD. For more info, see here.

- Slow Fibonacci Walks (with Fan Chung and Ron Graham). Submitted, 2019
- Random Graphs Induced by Catalan Pairs (with Daniël Kroes). Submitted, 2019.
- Ballot Permutations and Odd Order Permutations. Submitted, 2018.
- Saturation Games for Odd Cycles. Submitted, 2018.
- Polynomial Relations Between Matrices of Graphs. Journal of Graph Theory, 2018.
- Forbidden Families of Minimal Quadratic and Cubic Configurations (with Attila Sali). The Electronic Journal of Combinatorics, 2017.

For the Spring 2019 quarter I will be TAing Math 184A.
My office hours are Tuesday 12:00-1:00, and Fridays 1:30-2:30 and 4:00-5:00.
I am also available by appointment.
