Yizheng Xie

I’m a Ph.D. candidate at Brown University working on distributed systems, advised by Nikos Vasilakis in the Atlas Research Group. Before Brown, I worked with Vasiliki Kalavri and John Liagouris as part of CASP Lab at Boston University. I received my undergraduate degree from The Chinese University of Hong Kong, Shenzhen. I was also a Production Engineer intern in the Kernel Team at Meta.
