I am a third-year mathematics graduate student at the University of Washington. My advisor is Sara Billey. Before UW, I did my undergrad at Drexel University in Philadelphia, Pennsylvania. Go Birds. My mathematical interests are in algebraic combinatorics, graph theory, and symmetric functions. Outside of math, I enjoy skateboarding, watching movies, and exploring cities.

Research:

My primary research interest is the Stanley-Stembridge conjecture as well as other questions about chromatic symmetric functions.

Papers and Preprints:

• Noncommutative Schur functions for Posets (With Jonah Blasiak, Holden Eriksson, and Pavlo Pylyavskyy) Preprint, November 2022 arXiv. To appear in Selecta Mathematica.
• Cylindric P-Tableaux for (3+1)-Free Posets Preprint, November 2022 arXiv.
