Research Interest:

Algebra and Combinatorics: In algebra, I am mostly interested in the study of the phenomenon of non-uniqueness of factorizations into irreducibles in commutative cancellative monoids and integral domains using techniques of number theory, combinatorics, and convex geometry. My research in combinatorics focuses on matroids, in particular, positroids and tiling matroids. I am also interested in polytopes, cluster algebras, finite groups, and graphs.
