About

I'm Xuhao Luo (罗旭皓), a final-year Ph.D. candidate in the Siebel School of Computing and Data Science at University of Illinois Urbana-Champaign (UIUC). Currently I work with Prof. Aishwarya Ganesan and Prof. Ramnatthan Alagappan on distributed systems. Previously, I got my M.S. in Computer Science from UC San Diego, where I worked in WukLab with Prof. Yiying Zhang on operating systems, networking, and computer architecture.
