About
I am currently an Assistant Professor in the Department of Electrical and Computer Engineering
of Wayne State University.
I received my Ph.D. in ECE at Ohio State University, advised by Prof. Ness Shroff. Prior to that, I graduated from BUPT with
a B.S. and Tsinghua University with an M.S., both in
Electrical Engineering.
I have also been a machine learing engineer intern at Facebook and a research intern at Alibaba, USA advised by Jian Tan.
I am looking for self-motivated Ph.D. students. Drop me an email if you have an interest in working with me.
Research Overview
My research interests include both machine learning and stochastic systems. On the learning side, I mainly focus on Bayesian optimization, bandits and reinforcement learning. On the stochastic systems side, I primarily work on load balancing with applications in data centers and cloud computing.
