个人简介
I am interested in increasing the reliability of Distributed Systems. Building reliable distributed systems means guarding against both hardware and software failures. My research spans fault-tolerant replication and formal verification of systems software.
In my most recent projects, I have demonstrated how formal verification can be applied to complex distributed systems; how to verify high-performance cryptographic code; how to rethink replication protocols in the presence of service interactions; how to automate the verification of distributed protocols; introduced a new approach for verifying high-performance concurrent code; and demonstrated how one can reason formally about the performance of a distributed system.
In previous work, I have shown that the ACID paradigm is not fundamentally slow, but can be made to perform well if one separates the ACID guarantees from the mechanism that implements them; and I have shown how to rearchitect the 40-year-old idea of State Machine Replication to accommodate multithreaded execution.
These days, I mostly work on making formal verification practical by applying it to complex systems in new and interesting ways and by automating the process of proving the correctness (and performance) of these systems.
