ABOUT ISL




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 practical machine learning and deep learning
systems, 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.
