Wing Kam Liu is an American mechanical engineer and academic whose work focuses on computational mechanics, multiscale modeling, and mechanistic data science. He is the Walter P. Murphy Professor of Mechanical Engineering and Civil and Environmental Engineering at Northwestern University, with a courtesy appointment in Materials Science and Engineering. His research integrates physics-based modeling with data-driven methods for engineering analysis and design.[1]
Early life and education
[edit]Liu earned a Bachelor of Science in Engineering Science (with honors) from the University of Illinois at Chicago. He later completed both his Master of Science and Doctor of Philosophy degrees at the California Institute of Technology (Caltech), where his doctoral research emphasized computational mechanics and numerical methods for engineering applications.[1]
Academic career
[edit]Liu joined Northwestern University’s McCormick School of Engineering, where he has held senior academic appointments in mechanical engineering and theoretical and applied mechanics. Over the course of his career, he has supervised numerous doctoral students and postdoctoral researchers, many of whom have gone on to academic and industrial leadership positions.
His academic work spans computational mechanics, finite element and meshfree methods, multiscale modeling, and the integration of artificial intelligence with physics-based simulation tools.[1]
Research and scientific contributions
[edit]Liu’s research centers on the development of computational frameworks that integrate fundamental physical laws with large-scale data. He is associated with the advancement of mechanistic data science, an approach that combines physics-based modeling with machine learning to support predictive modeling, optimization, and design in complex engineering systems.
His work has contributed to methods that bridge atomistic, mesoscopic, and continuum scales, enabling efficient simulation of materials and structures across multiple length and time scales. Applications of his research include additive manufacturing, advanced materials, biomechanics, and engineering system optimization.
Technology development
[edit]Liu is associated with the development of HiDeNN-AI (Hierarchical Deep-learning Neural Network Artificial Intelligence), a research initiative focused on physics-informed artificial intelligence methods for engineering simulation and design. Building on this work, HiDeNN-SIM was developed as an engineering simulation platform that integrates physics-based modeling with data-driven techniques to support high-dimensional design exploration.
These technologies aim to reduce computational cost and improve efficiency in simulation-driven engineering workflows by combining mechanistic modeling with machine learning–based surrogate methods.
Patents
[edit]Liu is listed as an inventor or co-inventor on multiple granted and pending patents related to computational mechanics, multiscale materials modeling, and mechanistic artificial intelligence. These include U.S. and international patents covering hierarchical deep-learning neural networks, integrated process–structure–property modeling, and AI-enabled computational engineering tools.
Awards and honors
[edit]Liu has received numerous national and international honors, including:
- Gauss–Newton Medal, International Association for Computational Mechanics (2012)[2]
- John von Neumann Medal, U.S. Association for Computational Mechanics (2007)[2]
- Robert Henry Thurston Lecture Award, American Society of Mechanical Engineers (2007)[3]
- Computational Mechanics Award, Japan Society of Mechanical Engineers (2004)
- ASME Gustus L. Larson Memorial Award (1995)
- ASME Melville Medal (1979)
He has also been listed as a Highly Cited Researcher by the Institute for Scientific Information (ISI).[4][5]
Professional service
[edit]Liu has held leadership roles in international scientific organizations, including service as President of the International Association for Computational Mechanics and as President of the U.S. Association for Computational Mechanics. He has also served in editorial roles for several international journals in computational mechanics and applied mathematics.
