Research Interests

I am particularly excited about exploring the link between algebra and graph theory by translating algebraic problems into combinatorial questions about graphs, and vice versa. My graduate research unites discrete mathematics with representation theory and algebraic combinatorics through a generalization of the classical discrete Fourier transform to finite groups and semisimple algebras. I have developed efficient algorithms to compute generalized Fourier transforms and have also analyzed their applications to random walks. For more details, you can view my research statement here. You can also hear me talk about classical Fourier transforms here (starting around 1:36).
