I’m an assistant professor of Electrical and Computer Engineering and Computer Science (secondary appointment) at Duke University. I direct the Duke FuNCtions Lab, where we work on a variety of exciting research topics in next-generation wireless networks and systems. I am also the co-founder and Network Lead of WiLO Networks Inc., a start-up focusing on low-power sensor hardware and end-to-end systems. 

Before joining Duke, I was a postdoc in the Department of Electrical Engineering at Yale University in 2020-2021, working with Professor Leandros Tassiulas and Professor Lin Zhong. Before that, I received my Ph.D. degree in Electrical Engineering from Columbia University in 2020 (advisor: Professor Gil Zussman) and my B.Eng. degree in Electronic Engineering from Tsinghua University in 2014 (advisors: Professor Zhisheng Niu and Professor Sheng Zhou).

Interests: I am interested in the broad areas of future wireless networks and IoT systems. My recent research focuses on both theoretical and experimental aspects of massive antenna systems and millimeter-wave networks, optical-wireless networks, and their convergence with edge cloud and computing. I also enjoy building efficient hardware/software systems and experimental testbeds at scale.

Impacts: My research has been recognized by an IBM Academic Award, a Google Research Scholar Award, the Columbia Engineering Morton B. Friedman Memorial Prize for Excellence, the Columbia University Eli Jury Award, a Facebook Fellowship, and a Wei Family Private Foundation (WFPF) Fellowship. My Ph.D. thesis received the ACM SIGMOBILE Dissertation Award Runner-up. I also received the ACM CoNEXT 2016 Best Paper Award and the ACM MobiHoc 2019 Best Paper Award finalist. WiLO Networks Inc. is currently supported by an NSF SBIR Phased I award (IIP-2108012).

News: I am always looking for motivated and creative B.S., M.S., and Ph.D. students, as well as Postdocs to join my group in Duke ECE. If you are interested in topics related to next-generation wireless networks and systems, optical-wireless communications, AI/ML for networking, edge cloud, and IoT, please email me your CV, transcript, and a brief note about your research interests, and I would be happy to chat!
