Xinhao Kong



I am a second-year Ph.D. student in the Department of Computer Science at Duke University, advised by Prof. Danyang Zhuo. My research interests include cloud computing and datacenter networks, with a focus on kernel bypass networking and hardware acceleration.

Before Duke, I received my bachelor’s degree from Peking University. I am also fortunate to work with other excellent researchers and engineers, including Wei Bai, Mahmoud Elhaddad, and Shachar Raindel when I intern at Microsoft. I also worked closely with Yibo Zhu and Chuanxiong Guo when I was in ByteDance.


Jan 2023 - I will present Husky on NSDI 2023. See you in Boston!

July 2022 - Our RDMA performance isolation paper get accepted by NSDI 2023!

May 2022 - I start my internship @Microsoft Azure Host Networking Group. Let’s meet at the Puget Sound!

April 2022 - I will present Collie on NSDI 2022. See you in Seattle/Renton!
