I am an assistant professor in the Department of Electrical Engineering and an associated faculty member in the Department of Computer Science 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, convex and nonconvex optimization, high-dimensional data analysis, statistical learning and estimation, information theory, and their applications to medical imaging and computational biology.

Recent news
I am organizing a reading group on mathematical data science. Let me know if you are interested in attending and presenting. Note, however, that this reading group is (often) supposed to be mathematically intense.
Yuejie Chi and I gave a tutorial on ‘‘Taming Nonconvexity in Information Science’’ at ITW 2018.
I received the 2019 AFOSR Young Investigator Program (YIP) Award.
Mengdi Wang and I organized a workshop ‘‘Bridging Mathematical Optimization, Information Theory, and Data Science’’ at Princeton, May 2018.
