Biography
Starting in July 2025, I will be joining the Department of Computer Science (CS) at University of California, Santa Barbara. You can read my Q & A interview with UCSB College of Engineering.
I am an Assistant Professor in the Department of Electrical & Computer Engineering (ECE) at University of Florida.
Before joining the University of Florida, I was a postdoctoral research associate at the Research Laboratory of Electronics and Institute for Data, Systems, and Society (IDSS), Massachusetts Institute of Technology (MIT).
I received my Ph.D. degree at the Coordinated Science Laboratory and the Department of Electrical and Computer Engineering, University of Illinois at Urbana-Champaign (UIUC) in 2019. Before that, I received a B.S. degree (with honors) in Electronic Engineering from Tsinghua University in 2014.
Research
My research interests lie in the intersection of machine learning, information theory and signal processing. I leverage the tools from information theory and signal processing to develop theoretically justified learning algorithms for diverse applications, including watermarking generative AI, fair machine learning, uncertainty quantification, model compression.
More broadly, the primary goal of my research is to lay information-theoretic foundations for trustworthy learning algorithms, particularly with generalization, fairness, and robustness guarantees.
