Recruitment

Actively recruiting PostDoc researchers and Ph.D./Master students; please see the details. [Nov. 16, 2025]

Research Philosophy

& Current Focus

♥ Understanding fundamental and realistic problems of today's mobile/network/cloud systems at scale, as well as building principled solutions and usable tools to practically address them. Our research has led to actual effect on industrial systems including Alibaba Cloud, Android Cellular Management, Android Emulator, Baidu PhoneGuard, ByteDance Douyin/Toutiao, Tencent App Store, Tencent Game Buddy, Tencent Offline Downloading, UUSense, WiFi.com, Xiaomi Mobile, Xiaomi OS, etc.

♥ In particular, we strive towards reliable networking under harsh environments (such as highly-heterogenous cellular accesses, high-mobility subway trains, and high-throughput data centers), by means of large-scale characterization, in-depth optimization, and cost-efficient virtualization. Harsh environments stress every piece of the communication chain, and thus are where users suffer the most and reliability matters the most. In other words, it is in harsh environments that a network design is truly proven.
