About

Jay Lepreau was a pioneering force in experimental computer science, best known for founding the Emulab project—the world’s most widely used network testbed. His research centered on operating systems, networking, and distributed systems, with a particular passion for enabling realistic, repeatable experimentation. Lepreau’s major contribution was creating Emulab, a facility that allowed researchers to run controlled, reproducible experiments on real hardware, bridging the gap between simulation and deployment. This work revolutionized systems research, with Emulab supporting thousands of users and generating over 10,000 citations across related publications. He also advanced wireless and sensor networking through the Mobile Emulab and TrueMobile testbeds, integrating robotic mobility to capture real-world radio and sensor complexities. His 2006 paper on Mobile Emulab alone has garnered over 200 citations, underscoring its lasting impact. Lepreau’s achievements include receiving the SIGOPS Hall of Fame Award and the USENIX Lifetime Achievement Award, recognizing his relentless dedication to open, community-driven infrastructure. His legacy endures in every experiment run on Emulab and in the countless students and researchers he inspired to build, test, and share real systems.
