(https://superurop.mit.edu/scholars/mark-jabbour/) - Abstract: Writing correct distributed systems software is challenging because, in a distributed system, individual machines can fail and recover while others continue working, and because different machines execute concurrently. As a result, subtle and easy-to-miss bugs can lead to serious problems. This project's goal is to explore the use of formal verification to develop, specify, and verify correctness of distributed systems implementations and applications.
