Welcome!
I am a professor of Materials Science and Engineering at Huazhong University of Science and Technology since 2021.
I am a professor of Materials Science and Engineering at Huazhong University of Science and Technology since 2021.
I received my Ph.D. in Condensed Matter Physics advised by Prof. Brahim Dkhil from CentraleSupélec, Université Paris-Saclay in 2016. I was a post-doctoral fellow at the Pennsylvania State University working with Prof. Qing Wang from 2016-2021.

My current research interests lie in physics and engineering of polymers and composites for electromechanical devices, understanding of unusual relaxor behavior in ferroelectric polymers, interface engineering of dielectric polymer nanocomposites for capacitive energy storage devices, and integration of caloric materials for solid-state refrigeration.
