Research Interests
I am a die-hard combinatorialist. My current research is in geometric combinatorics with connections to applied algebraic geometry and optimization. I am studying realization spaces of polytopes and matroids. In particular, I am interested in correspondence between the algebraic properties of slack ideals and the geometric and combinatorial structure of the polytopes and matroids.
I also still think about problems and objects that have applications in digital communication. In the past, I have studied Golay sequences and arrays, peak sidelobe levels of binary sequences, and I wrote my Master's thesis on the subject of complex equiangular lines (also known as SIC-POVMs to those studying quantum information theory).
