Huajian Gao received his B.S. from Xian Jiaotong University in 1982, and his M.S. and Ph.D. from Harvard in 1984 and 1988, respectively. His spent his academic career at Stanford (1988-2002), Max Planck Institute for Metals Research (2001-2006), Brown (2006-2019) and NTU (2019-present). His research has been focused on the understanding of basic principles that control mechanical properties and behaviors of materials in both engineering and biological systems. He has been elected to the US National Academy of Sciences and US National Academy of Engineering. His major awards include the Rodney Hill Prize from the International Union of Theoretical and Applied Mechanics, one of the highest honors in his field.
Huajian Gao developed theories and made fundamental discoveries that laid the foundation for nanomechanics of engineering and biological systems, a new field he helped create during the past three decades. His research covers a wide range of topics, including fracture mechanics, thin film mechanics, plasticity, indentation size effect, stress assisted diffusion, dynamic fracture, mechanics of hierarchically structured biological materials, biological adhesion, cell mechanics, endocytosis, cell-nanomaterials interaction, membrane targeting antimicrobials, mechanics of hierarchical nanotwinned materials, and mechanical degradation in lithium ion batteries. His work aims to redefine the modern frontiers of mechanics research.
Gao does mechanics research related to new materials, energy and health technologies.
