About Me

Dr. Dehui Wei is a Senior Researcher at Microsoft Research Asia. Before joining Microsoft, she was a Postdoctoral Research Fellow at the National University of Singapore (NUS). She received her Ph.D. in Information and Communication Engineering from Beijing University of Posts and Telecommunications (BUPT), advised by Prof. Jiao Zhang.

Dr. Wei has published her research at top networking venues, including USENIX NSDI, IEEE INFOCOM, and IEEE JSAC, covering topics such as large-scale edge CDN infrastructures, multipath scheduling, congestion control, and Internet-scale overlay networks. Her current research focuses on intelligent scheduling and orchestration for AI-agent applications.
