About: I am a fifth-year stat­istics PhD stu­dent at the Univ­ersity of Wisc­onsin–Mad­ison rece­iving acad­emic guid­ance from Prof­essor Joshua Cape.

I am interested in the statistical inference of latent low-dimensional objects and low-rank structures hidden in noisy high-dimensional data. The focus of my research has been on fine-grained asymptotic and non-asymptotic distributional analyses of spectral embeddings in the matrix denoising model.
