My research aims to elucidate the fundamentals of light-molecule, colloid-fluid, and opto-thermo-matter interactions at an ultrahigh resolution and develop versatile optical diagnostic platforms to tackle critical technological challenges in materials science, electronics and photonics, energy and environment, and bioengineering

I am a postdoctoral scholar in the Department of Mechanical Engineering at the University of California, Berkeley. I obtained my Ph.D. in materials science and engineering from The University of Texas at Austin and B.Sc. in applied physics from the University of Science and Technology of China.
