The Internet Systems Lab (ISL) at the University of Colorado, led by Dr. Sangtae Ha, is researching all things having to do with the Internet. Our research focuses on building and deploying theory-inspired practical systems that span multiple disciplines, including networks and distributed systems, network optimization, cloud and edge computing, Internet protocols and algorithms, mobile systems, wireless and cellular networks, and storage systems. The ISL is located at the engineering building (ECCR1B05) and is part of the Computer Systems Group at the University of Colorado Boulder.
