I study spectral methods, and their applications in modern multivariate statistics. Furthermore, I am interested in the acceleration of statistical algorithms via randomized numerical linear algebra. My investigations often involve networks, random graphs/matrices, and point clouds, all with some low-dimensional latent structure. I am receiving academic guidance from Professor Joshua Cape.
