I am a second year math PhD student at UC San Diego. Here is my CV.

I am interested in algebraic combinatorics and representation theory.

Currently Working On

• Reading "Young Tableaux" by William Fulton
• Finding a representation-theoretic interpretation for the Schur positivity of "Chern Plethysm", as described in this paper by Sara C. Billey, Brendon Rhoades, and Vasu Tewari

Notes/Talks

• A classification of the indecomposable representations of the D4 quiver (oriented with all arrows pointing inward. Note that there are 12 distinct indecomposables.): D4
• Computing the path algebras of two different orientations of A3, and comparing them to the endomorphism algebras of a certain representation: Path algebras
• Every Counterexample Appearing in the Book Counterexamples in Topology and Whether or Not Each One is Compact: Slides
