Strong Representation At OSDI, Including Three Honors, Shows The Impact Of Brown Systems

The 20th USENIX Symposium on Operating Systems Design and Implementation (OSDI 2026), held this week from July 13-15 in Seattle, is widely considered a premier forum for discussing the design, implementation, and implications of software systems. This year, the Brown Systems research group has broken their own record with four accepted papers. One of these (“Controlling Opaque-Component Effects with Semisolates and Try”) won both a Jay Lepreau Best Paper Award (one of three awarded out of 136 accepted papers) and a Best Artifact Award (one of three awarded out of 136 papers), and another (“RT: Regular Types for the Streaming Shell”) was a Best Paper Award Runner-Up (one of nine). Brown Systems students also presented six posters (25% of the total 24) at the OSDI poster session.

The common thread linking all four papers is Brown CS faculty member Nikos Vasilakis (also affiliated with Brown’s Data Science Institute) and his ATLAS research group, which builds systems that lift the capabilities of programmers dealing with the vast complexity of modern software systems, automating away inessential complexity and automating in desired features. Their recent honors include a Best Paper Award from the final USENIX ATC conference, a Google ML-and-Systems Junior Faculty Award on securing open-source software, and an Amazon Research Award on automated reasoning for the Unix/Linux shell.

For the following, Brown CS faculty, students, and alums are shown in bold:
