===== About Me =====

I am an assistant professor in School of Software, Shanghai Jiao Tong University (SJTU). I received my bachelor's degree in software engineering from SJTU in 2016, and my Ph.D. degree in computer science from SJTU in 2021, advised by Prof. Haibo Chen, Prof. Yubin Xia, and Prof. Binyu Zang. My research mainly focuses on Operating Systems and Systems Security. My recent project is building a microkernel-based OS named ChCore targeting new scenarios.
