I design online algorithms with provable performance guarantees for practical networking systems.

I received my Ph.D. from the University of Science and Technology of China (USTC) in 2023, supervised by Prof. Xiang-Yang Li and Prof. Haisheng Tan. I am also a Humboldt Research Fellow, awarded the fellowship in 2023 with Prof. Xiaoming Fu as my host.

My research focuses on online problems in mobile edge computing and data center networks, including flow scheduling, job scheduling, and file caching. I develop online solutions with performance guarantees for practical networking problems. My work has appeared in IEEE/ACM ToN, IEEE INFOCOM, ACM MobiHoc, and IEEE ICDCS. I also serve as a reviewer for IEEE TMC and IEEE TNSE.

博士，洪堡学者，现为合肥工业大学计算机与信息学院副教授。博士毕业于中国科学技术大学，导师为李向阳教授和谈海生教授。主要研究移动边缘计算和数据中心网络中的在线问题，包括流调度、任务调度、文件缓存等，旨在针对实际中的网络问题提供具有理论性能保证的在线解决方案。相关研究成果发表在 IEEE/ACM ToN、IEEE INFOCOM、ACM MobiHoc 及 IEEE ICDCS 等计算机网络与分布式领域的国际顶级期刊和会议上，并担任 IEEE TMC 和 IEEE TNSE 期刊审稿人。
