I am currently a Postdoctoral Research Associate at UMass CICS, working with Prof. Mohammad Hajiesmaili. Before joining UMass, I received my Ph.D. from the Institute for Interdisciplinary Information Sciences (IIIS), Tsinghua University, where I was supervised by Prof. Zhixuan Fang. Prior to that, I achieved my Bachelor’s degree at the Department of Electronic Engineering of Tsinghua University and worked with Prof. Wenfei Wu.
