Tingjun Chen (陈廷钧)

Graduated 2020
Thesis: Algorithms and Experimentation for Future Wireless Networks: From Internet-of-Things to Full-Duplex

I received my Ph.D. degree in Electrical Engineering from Columbia University in 2020, where I worked at the Wim.Net Lab with Professor Gil Zussman. My research interests are in the areas of future wireless networks and systems, including the Internet-of-Things (IoT), energy harvesting networks, full-duplex wireless, massive antenna systems, millimeter-wave networks, and optical-wireless networks and edge cloud. In particular, my research focuses on emerging communication technologies and their interactions with the higher layers (e.g., the medium access control layer and application layer), as well as their performance evaluation using custom-designed prototypes and testbeds.

I graduated with a B.Eng. degree in Electronic Engineering from Tsinghua University, China, in 2014, and received an M.S. degree in Electrical Engineering from Columbia University in 2015. I am the student co-lead of the Columbia FlexICoN project and am highly involved in the design and deployment of the NSF PAWR COSMOS testbed. I was also involved in the Columbia EnHANTs project.

I received the Facebook Fellowship in Networking and Connectivity, the Wei Family Private Foundation (WFPF) Fellowship, the Columbia Engineering Oscar and Verna Byron Fellowship, and the Columbia University Electrical Engineering Armstrong Memorial Award and Jacob Millman Award. I also received the ACM CoNEXT 2016 Best Paper Award and the ACM MobiHoc 2019 Best Paper Finalist.

News: I will be joining Duke’s Department of Electrical and Computer Engineering as an assistant professor in Fall 2021. If you are interested in working with me or potential collaborations – feel free to reach out! If you would like to know more about my current research, please refer to my research statement below. I am currently a postdoctoral associate at Yale working with Professors Leandros Tassiulas and Lin Zhong.

News: I am looking for motivated and creative B.S., M.S., and Ph.D. students to join my group at Duke starting in Fall 2021. If you are interested in topics related to next-generation wireless networks, edge cloud, systems, and IoT, please email me your CV, transcript, and a brief note about your research interests, and I would be happy to chat!
