## Biography

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