Ruochen Lu is an assistant professor and Fellow of the Silicon Laboratories Endowed Chair in Electrical Engineering in the Chandra Family Department of Electrical and Computer Engineering at The University of Texas at Austin. He received the B.E. degree with honors in microelectronics from Tsinghua University in 2014 and the Ph.D. degree in electrical engineering from the University of Illinois Urbana-Champaign in 2019.

His research focuses on piezoelectric MEMS and acoustic microsystems for signal processing, sensing, and computing. His group develops thin-film piezoelectric resonators, filters, and RF front-end technologies spanning microwave, millimeter-wave, and sub-THz frequencies. Complementary research directions include ultrasonic transducers, nonlinear phononics, piezoelectric power conversion, and heterogeneous integration of acoustics with electronic, photonic, magnetic, and quantum systems.

His honors include the IEEE MTT-S Microwave Award in 2022, the IEEE Ultrasonics Early Career Investigator Award and NSF CAREER Award in 2024, and the Transducer Research Foundation Rising Star of Microsystems Award in 2026. He serves as an associate editor for IEEE JMEMS, IEEE Transactions on Ultrasonics, IEEE Journal of Microwaves, and IEEE Electron Device Letters.
