Menglong Liu joined Harbin Institute of Technology (Shenzhen) in 2019 as an Assistant Professor and is currently an Associate Professor. Prior to this, he served as a Research Scientist at the Institute of High Performance Computing, A*STAR, Singapore (2017–2019). He earned his Ph.D. in Mechanical Engineering (Acoustics and Vibration) from The Hong Kong Polytechnic University in 2017, his Master’s in Measurement Technology and Instrumentation, and his Bachelor’s in Aircraft Design and Engineering from the Nanjing University of Aeronautics and Astronautics. His research interests mainly include the modeling of physical guided and bulk waves for nondestructive testing and structural health monitoring. Building on his expertise in piezoelectric materials for sensing and actuation in these applications, he has recently extended his research to the development of piezoelectric-driven electromechanical–magnetic antennas for ELF cross-medium communication.
