J. S. Chen’s research interests center around Computational and Applied Mechanics, with a focus on development of advanced Finite Element and Meshfree Methods for dynamic and nonlinear mechanics of materials and solids. His research activities include development of mathematical foundations and numerical formulations for multi-scale materials modeling, large deformation and contact mechanics, strain localization and material instabilities, microstructure evolution in polycrystalline materials, defects in materials at various length scales, computational bio mechanics, and computational quantum mechanics. His recent research focuses on physics-preserving reduced order approaches and machine learning enhanced data-driven computational mechanics for multi-physics multi-scale modeling of nonlinear materials and their applications to musculoskeletal digital twins.

J. S. Chen is currently the William Prager Chair Professor of Structural Engineering Department, and Professor of Mechanical and Aerospace Engineering Department. Before joining UCSD in October 2013, he was the Chancellor’s Professor of UCLA Civil & Environmental Engineering Department where he served as the Department Chair during 2007-2012, and was also the Professor of Mechanical & Aerospace Engineering Department and Mathematics Department at UCLA. He is the Past President of US Association for Computational Mechanics (USACM) and the Past President of ASCE Engineering Mechanics Institute (EMI). He has received numerous awards, including the Computational Mechanics Award from International Association for Computational Mechanics (IACM), Grand Prize from Japan Society for Computational Engineering and Science (JSCES), the Ted Belytschko Applied Mechanics Award from ASME Applied Mechanics Division, the Belytschko Medal, U.S. Association for Computational Mechanics (USACM), among others. He is the Fellow of USACM, IACM, ASME, EMI, SES, ICACM, and ICCEES.
