About

Chang Lou is a tenure-track assistant professor in Department of Computer Science at University of Virginia. His research interests are distributed systems, operating systems, and cloud computing. His work centers on improving system reliability and availability. A major focus is enhancing the capabilities of cloud systems to detect, localize, and respond to complex failures during runtime. He has published multiple works on top system conferences including OSDI, NSDI, and ATC. His contributions received recognition including USENIX NSDI Best Paper Award in 2020 for his work on partial failures. In addition, his research on handling memory leaks in cloud infrastructure has been successfully deployed across millions of servers within Microsoft Azure.

News: Our lab has multiple Ph.D. student positions starting from Fall 2024. If you are interested in building/hacking systems, we should talk. Learn More
