My research interests span a broad range of topics related to systems, including distributed systems, operating systems, fault tolerance, file and storage systems, and packet classification. Specifically, I have been working on developing novel protocols/algorithms/techniques for building reliable distributed systems and demonstrating practicality of these approaches by incoprorating these ideas into file and storage systems. Prior to that I worked on operating system support for exploiting increasing h/w resources (h/w threads, cores, caches) in next-generation multi-core/multi-threaded processors to extract high performance while meeting new challenges arising from power constraints, increasing cpu-memory gap, etc.
