2. Brief Introduction

I received my Ph.D. in 2018 from the University of Electronic Science and Technology of China (UESTC), with a joint training period at the University of Virginia, USA. My research focuses on the design of high-performance integrated and semi-integrated microwave and millimeter-wave circuits. I have participated in the design and development of several major projects related to microwave, millimeter-wave, and terahertz technologies at the University of Virginia, The Chinese University of Hong Kong, and Southern University of Science and Technology. My scientific work centers on the design and synthesis techniques of reconfigurable microwave/millimeter-wave devices and integrated reconfigurable circuits in planar, cavity, and IC configurations. I pioneered a comprehensive advanced synthesis theory and design methodology for adaptive microwave circuits, which has been successfully applied to the practical implementation of various microwave components including tunable filters, multiplexers, power dividers, oscillators, and amplifiers. This work has effectively bridged the gap between theoretical concepts and engineering implementation in multifunctional adaptive microwave circuits. To date, I have co-authored one English monograph, filed two invention patents, and published over 50 SCI/EI-indexed papers. Among these, 13 first-author or corresponding-author papers were published in top-tier microwave journals classified as Chinese Academy of Sciences Zone 1, including IEEE Transactions on Microwave Theory and Techniques and IEEE Transactions on Circuits and Systems I: Regular Papers. I have led a National Natural Science Foundation of China (NSFC) Youth Project and served as a key participant in one major project of the Ministry of Science and Technology and several Shenzhen Key Laboratory projects.
