# Research Interests

I primarily work in extremal combinatorics. More specifically, I am interested in the application of tools from linear algebra, discrete Fourier analysis and other areas of mathematics to solve extremal combinatorial questions. I particularly enjoy finite intersection problems and their connections to other areas of mathematics like association schemes. I also have an interest in algebraic combinatorics.

I have also previously done work in enumerative combinatorics and discrete mathematics.
