I am a Professor in the School of Computer Science and Technology at Shandong University, where I co-lead the Blockchain and Distributed Security Lab with Prof. Xiuzhen Cheng. I joined Shandong University as an Assistant Professor (2021–2023), was promoted to Associate Professor (2023–2024), and received early promotion to Full Professor in 2024. I received my Ph.D. in Computer Science from The George Washington University (2018-2021) and my B.S. in Physics from Beijing Normal University (2014-2018). I was also a visiting scholar at ETH Zurich. |
