PNW PLSE

PNW PLSE will return for 2027! Please join our mailing list for updates!

PNW PLSE 2026 took place on May 5th at the Bill & Melinda Gates Center for Computer Science & Engineering in Seattle, WA.

The Pacific Northwest Programming Languages and Software Engineering (PNW PLSE) workshop provides an opportunity for programming languages and software engineering researchers throughout the Pacific Northwest to meet, interact, and share work in progress as well as recent results. Meetings will feature talks and demonstrations of current projects, provide opportunities to get feedback on exciting new projects, and generally foster connections that strengthen our vibrant research community in the region.
