I am an assistant professor of Electrical Engineering, and an associated faculty member of Computer Science, Applied and Computational Mathematics, and the Center for Statistics and Machine Learning at Princeton University.
Prior to joining Princeton in Spring 2017, I was a postdoctoral scholar in the Department of Statistics at Stanford University supervised by Prof. Emmanuel Candès. I completed my Ph.D. in Electrical Engineering at Stanford University in Fall 2014, under the supervision of Prof. Andrea Goldsmith.
Research areas: mathematical data science, statistics, reinforcement learning, optimization, information theory, and their applications to medical imaging and computational biology.

Openings
I'm looking for highly motivated postdocs with strong mathematical background and interest in the general areas of
high-dimensional statistics, nonconvex optimization, and reinforcement learning.
