英文简介

  • Weijian Jiao joined the School of Aerospace Engineering and Applied Mechanics at Tongji University as a Distinguished Research Fellow since September 2023. Prior to that, he was a Postdoctoral Fellow at the University of Pennsylvania (Advisor: Jordan R. Raney). He obtained his PhD in Civil Engineering from the University of Minnesota Twin Cities in 2020 (Advisor: Stefano Gonella). His current research focuses on nonlinear waves and their implications in the context of periodic structures and artificially architected materials, such as acoustic, elastic, and mechanical metamaterials. He has investigated a variety of nonlinear wave phenomena, ranging from finite-amplitude nonlinear harmonic waves to solitary waves to large-amplitude transition waves. In addition to providing fundamental understanding, he has devoted efforts to leveraging these nonlinear phenomena for practical implications, such as tunable acoustic devices, energy harvesting, reconfigurable/deployable structures, mechanical logic gates, and soft robotics. He has published more than 10 peer-reviewed journal papers, including Nature Communications, Science Advances, JMPS, Physical Review Applied/B/E, Proceedings of the Royal Society A, etc.
