About me
I am a final year Ph.D. student at the Department of Statistics, University of Washington, under the supervision of Professor Jon A. Wellner.
I am broadly interested in mathematical statistics and high dimensional probability. My current research is concentrated on abstract empirical process theory, and its applications to nonparametric function estimation (with a special focus on shape-restricted problems), Bayes nonparametrics, and high dimensional statistics.
My CV can be found here.
