BIOGRAPHY

Dr. Junrui Liang has received his B.S. and M.S degrees in Instrument Science and Engineering from Shanghai Jiao Tong University, and his Ph.D. degree in Mechanical and Automation Engineering from The Chinese University of Hong Kong in 2010. Since November 2013, he is with the School of Information Science and Technology, ShanghaiTech University as an Assistant Professor and Principal Investigator. His most significant contribution was that he extended the impedance modeling and analysis, which conventionally was only used for linear systems, to some nonlinear power conversion systems such as the class-E power amplifier and piezoelectric energy harvesting systems. He has also developed several innovative circuit solutions for the electromechanically coupled kinetic energy harvesting systems. His recent research interests include: power solutions for IoT devices, power management integrated circuits, kinetic energy harvesting technology and vibration control, mechatronics and electromechanical energy conversion, embedded systems and human factored IoT solutions, etc. Since 2008, Dr. Liang has published more than 40 peer-reviewed technical papers in international journals and conferences. He has received four research awards including the Best Student Contributions Award in the 2008 International Conference on Adaptive Structures Technologies, Best Paper Award in Automation in the 2009 IEEE International Conference on Information and Automation, Best Information Paper Award in the 2010 IEEE International Conference on Information and Automation, and Postgraduate Research Output Award 2010 from The Chinese University of Hong Kong. Dr. Liang is a member of IEEE (Institute of Electrical and Electronics Engineers), ASME (American Society of Mechanical Engineers), and CPSS (China Power Supply Society). He currently serves as an Associate Editor of the SCI indexed journal IET Circuits, Devices & Systems. He is also a member in the Program Committee of SPIE Smart Structures/NDE conference, Technical Committee of Power and Energy Circuits and Systems in the IEEE Circuits and Systems Society, and Energy Harvesting Technical Committee in Adaptive Structures and Material Systems Branch of ASME Aerospace Division.
