I am an Assistant Professor in the School of Artificial Intelligence at Beijing University of Posts and Telecommunications (BUPT). I received my Ph.D. from Tsinghua University in 2024 under the supervision of Prof. Zheng Yang. Before joining BUPT, I was a postdoctoral researcher at Tsinghua University, working with Prof. Yunhao Liu. I received my B.E. from BUPT in 2019.
My research focuses on IoT sensing, communications, and embodied navigation systems. My work has appeared in ACM MobiCom, ACM MobiSys, and IEEE JSAC. I lead projects supported by the NSFC Young Scientists Fund (Category C) and the General Program of the China Postdoctoral Science Foundation.
I received the 2026 CCF Natural Science Award, First Prize, the ACM MobiCom 2024 Best Artifact Award, and the ACM SIGCOMM China Doctoral Dissertation Award.
