About
I am a Ph.D. Candidate in Mechanical Engineering at the Georgia Institute of Technology, advised by Prof. Ting Zhu. My research lies at the intersection of Solid Mechanics and Materials Science, employing computational methods to unravel the physical mechanisms governing material behavior from the atomic to the continuum scale.
Profile
"Bridging the gap between nano-scale physics and macro-scale applications to design the next generation of resilient materials."
My academic journey began at SUSTech (B.Sc. in Theoretical and Applied Mechanics), where I developed a strong foundation in fracture mechanics under the guidance of Prof. Wei Hong. Currently, my doctoral work focuses on Multiscale modeling, specifically investigating crystal plasticity, grain growth, and the mechanical degradation of solid-state electrolytes.
