Ruochen Lu is an Assistant Professor in the 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, Beijing, China, in 2014, and the Ph.D. degree in electrical engineering from the University of Illinois at Urbana-Champaign, Urbana, IL, USA, in 2019.

His research focuses on microelectromechanical systems (MEMS) that advance chip-scale acoustic and electromagnetic components for microwave signal processing, sensing, and computing. His group develops thin-film piezoelectric platforms and RF front-end microsystems that push operating frequency and transduction efficiency while tightly integrating acoustics with electronics. Complementary thrusts include ultrasound transducers, multiphysics microsystems that couple acoustics with optics and magnetics, engineered nonlinearity/nonreciprocity, along with biomedical, quantum, and power-conversion applications.

He received the IEEE MTT-S Microwave Award in 2022, the IEEE Ultrasonics Early Career Investigator Award in 2024, and the NSF Career Award in 2024. He received the Junior Faculty Excellence in Teaching Award from the University of Texas at Austin in 2024. He is an associate editor of the IEEE Journal of Microelectromechanical Systems, the IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, and the IEEE Journal of Microwaves.
