Portrait of Yizheng Xie
I’m a Ph.D. candidate at Brown University advised by Nikos Vasilakis in the Atlas Research Group. My research interests include distributed systems, operating systems, and cloud computing—with a particular focus on performance prediction and optimization for modular software architectures such as microservices, serverless platforms, and the shell. 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.
