张弛，博士（导师：李向阳，谈海生），现为合肥工业大学计算机与信息学院副教授。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/分布式领域的国际顶级期刊和会议上，并担任期刊IEEE TMC审稿人。

I received my Ph.D. degree from the University of Science and Technology of China (USTC) in 2023 (supervised by Prof. Xiang-Yang Li and Prof. Haisheng Tan). I am currently an associate professor at the School of Computer Science and Information Engineering, Hefei University of Technology. Recently I am mainly working on online problems in mobile edge computing and data center networks, including flow scheduling, job scheduling, and file caching, aiming at online solution with performance guarantees for practical networking issues. My related research findings have been published in top-tier international journals and conferences in the fields of computer networks/distributed systems, such as IEEE/ACM ToN, IEEE INFOCOM, ACM MobiHoc, and IEEE ICDCS. I also serve as a reviewer for the IEEE TMC journal.
