Charlottesville, Virginia, United States
Summary
👤
Senior🎓
Top SchoolChang Lou is a tenure-track assistant professor in computer science at the University of Virginia with a decade of experience building robust, highly available distributed systems. His research and engineering work focuses on making distributed services detect, localize, and react to complex runtime failures, drawing on a PhD from Johns Hopkins and internships at Microsoft Research Asia and Columbia. He has practical systems experience contributing to the well-known rDSN framework—fixing replication tutorials, improving profiling tools, and hardening backend code—which informs his hands-on approach to research. Prior projects span cloud service availability, graph-query optimization using hardware features, and tooling to find kernel data races, reflecting a blend of theory and production-grade engineering. Based in Charlottesville, he combines academic rigor with pragmatic contributions to open-source and cloud systems.
