I am an assistant professor in the Department of Computer Science at Rutgers University, where I direct a Machine Learning Lab. Previously I was a Postdoctoral Research Associate at Computer Science & Artificial Intelligence Lab of Massachusetts Institute of Technology, working with Prof. Dina Katabi and Prof. Tommi Jaakkola. I obtained Ph.D degree in CSE department, Hong Kong University of Science and Technology. My supervisor was Prof. Dit-Yan Yeung. I was a visiting scholar working with Prof. Eric Xing's group in Machine Learning department of Carnegie Mellon University. I am also a Microsoft Fellow and received the Baidu Research Fellowship. Before my Ph.D, I got my BS degree from Shanghai Jiao Tong University, 2013 under the supervision of Prof. Wu-Jun Li.

Recruiting: I am recruiting PhD students starting from Fall 2025 as well as interns. Send me an email if you are interested in working with me at Rutgers.

My research interest focuses on statistical machine learning and deep learning. Currently, I mainly work on Bayesian deep learning, probabilistic methods, game-theoretic approaches, and their applications in trustworthy & safe AI (interpretability, robustness, alignment, etc.), healthcare, recommender systems, computer vision (including LMM), natural language processing (including LLM), network analysis, and data mining.
