UW PLSE

UW CSE’s Programming Languages and Software Engineering group advances fundamental research and practical applications (some in this GitHub organization) in programming environments, program analysis, language design, synthesis, compilers, testing, verification, and security. We have strong ties to the Sampa and SAMPL groups, Intel, Cray, Microsoft Research, NVIDIA, AT&T, and others.
