The UNSAT group aims to develop foundational technologies for improving the correctness and performance of practical computer systems. Our research spans the areas of formal methods, programming languages, and operating systems. We build verification and synthesis tools and use these tools to build efficient, reliable, and secure systems. We are part of the Paul G. Allen School at the University of Washington. See our papers and projects for more details about our research.

If you are interested in joining our group, see the page for prospective students. We currently don’t have any positions for internships, visiting scholars, or postdocs.



Published a technical report on building security monitors on RISC-V and our experience with using the HiFive Unleashed.


Our paper on fixing performance bottlenecks in code under symbolic evaluation will appear at VMCAI 2020.


Our paper on scaling automated verification with Serval won a best paper award and a distinguished artifact award at SOSP 2019.
