What we do

We conduct research on large-scale distributed systems and networking. Our approach is mainly experimental, focusing on the design, deployment and evaluation of systems that people use. Much of our work is guided by the unique perspective provided by devices at the edge of the Internet and captured through our users/collaborators who adopt and use our software. We are driven by a desire to provide solutions to real network and systems problems, while we also take pleasure in the scientific and engineering contributions that we make.
