I’m currently a Postdoctoral Researcher at Indiana University Bloomington, under the supervision of Prof. XiaoFeng Wang and Prof. Haixu Tang.

Before joining Indiana University, I completed my Ph.D. in Computer Software and Theory from Peking University in January 2023, advised by Prof. Zhonghai Wu. During my doctoral studies, I also had the enriching opportunity to serve as a visiting scholar at the CISPA Helmholtz Center for Information Security from 2019 to 2020.
