I am an NSF Graduate Research Fellow in my third year as a mathematics PhD student at the University of Illinois at Urbana-Champaign. I am interested in algebraic combinatorics, and my advisor is Alexander Yong. I am a co-organizer for the University of Illinois Algebra-Geometry-Combinatorics Seminar.

Research Interests

  • Algebraic Combinatorics

Research Description

In algebraic combinatorics, I am interested in Schubert calculus as well as related problems in geometry, representation theory, and computational complexity.
