Xibi Chen is a Ph.D. student in the Terahertz Integrated Electronics Group at MIT. He received his B.S. and M.S. degrees from Tsinghua University, Beijing, China, in 2017 and 2020, respectively. From 2015 to 2017, he was a Research Assistant with the Microwave and Antenna Institute, Department of Electronic Engineering, Tsinghua University. He later became a Graduate Student Researcher in the same institute from 2017 to 2020. His research background includes terahertz (THz) integrated circuits and systems, electromagnetics, advanced packaging technologies, large-scale phased arrays, radar sensing, and high-speed communications. He worked in Texas Instruments (Kilby Lab) and Intel Corporation as Summer Research Interns in 2023 and 2024, respectively. Xibi was the recipient of the 2025–2026 IEEE SSCS Predoctoral Achievement Award, and the 2024 IEEE MTT-S Tom Brazil Graduate Fellowship. He also received the 2025 MIT EECS MathWorks Fellowship Award, ISSCC 2022 Student Travel Grant Award, and Analog Devices Outstanding Student Designer Award.
