Hi! I’m Ziqi Zhang (pronounced as /tzi’chi chang/). I’m currently a Postdoc Researcher at UIUC working with Lingming Zhang. I received my Ph.D degree in the School of Computer Science from Peking University in 2023, advised by Prof. Ding Li, Prof. Yao Guo and Prof. Xiangqun Chen. Before that, I earned my bachelor’s degree from the School of EECS, Peking University.
