My name is Qiuyu Xiao (Chinese: 肖秋雨). I am a research scientist in Facebook. I got my Ph.D. from UNC-CH CS department in 2019, and was fortunate to be advised by Dr. Michael Reiter. I got my B.S. degree from Shanghai Jiao Tong University in 2014.

My previous research projects include:

  • A cloud-based privacy-enhancing service to prevent user’s web activities from being monitored by employers or ISPs ([Pub. 1]).
    • This system guarantees “server anonymity” to the user. ISPs that slow down your traffic to certain websites or collect your web browsing history can be defeated by our system.
  • A theoretical framework to defend against side-channel attack ([Pub. 2]).

I interned at VMware in 2018 (mentored by Dr. Ben Pfaff) and Huawei in 2017 (mentored by Dr. Haibo Chen).

Open Source Project

I interned at the VMware Open vSwitch team in the summer of 2018. During my internship, I workded on adding tunnel encryption support for Open vSwitch and Open Virtual Network by using IPSec.

The goal is to bring end-to-end encryption for tunneling traffic between hypervisors and also offer an easy-to-use interface for administrators to configure encryption. I gave a talk on this topic in the 2018 Open vSwitch Conference. You can check my talk and slides here.


When I’m not working on computer science, I like to read books, watch movies, travel around, play board games, and hang out with friends.
