I’m an assistant professor of Electrical and Computer Engineering and Computer Science (secondary appointment) at Duke University. I direct the Duke FuNCtions Lab, working with a group of talented students on a variety of exciting research topics in next-generation wireless, optical, and mobile networks as well as edge computing 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/mobile/optical 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, computing, and AI/ML systems. I also enjoy building efficient hardware-software systems and experimental testbeds at scale.

Impacts: My research has been recognized by two IBM Academic Awards (2023, 2021), a Google Research Scholar Award (2021), the Columbia Engineering Morton B. Friedman Memorial Prize for Excellence (2021), the Columbia University Eli Jury Award (2021), a Facebook Fellowship (2019), and a Wei Family Private Foundation (WFPF) Fellowship (2014). I have received multiple paper awards from IEEE/Optica OFC’24 (Top-Scored Paper), IEEE/Optica OFC’23 (Top-Scored Paper), ECOC’23 (Highest Scoring and Best Paper), ACM CoNEXT’16 (Best Paper Award), ACM MobiHoc’19 (Best Paper Finalist), and IEEE MTT-S IMS’19 (Advanced Practice Paper Finalist). My Ph.D. thesis received the ACM SIGMOBILE Dissertation Award Runner-up. 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!
