My name is Qiuyu Xiao (Chinese: 肖秋雨). My first name can be pronounced as Cho-U. I got my Ph.D. degree from The University of North Carolina at Chapel Hill in 2019 (advised by Dr. Mike Reiter) and B.S. degree from Shanghai Jiao Tong University in 2014 (advised by Dr. Haojin Zhu). During my Ph.D. years, I also did internship in VMWare Open vSwitch team (mentored by Dr. Ben Pfaff) and Huawei OS Kernel Lab (mentored by Dr. Haibo Chen).

I have broad interests in AI systems, distributed systems, operating systems, security and privacy. During my Ph.D. years, I did research on designing novel algorithms and building secure systems to protect user privacy.

Currently, I'm a research scientist in Meta (Facebook), where I am working on building large-scale distributed systems to solve various interesting problems, including:

• Build a metadata caching and delivery system for reliable dynamic configuration and service discovery
• Build a P2P data streaming system for improving model freshness
