In the UTNS (formerly WISR) research group we work on building software systems that improve the performance, efficiency, and correctness of modern cloud computing infrastructure and applications. Our current focus is on systems for big data processing, machine learning and inference, ultra-low latency networking, serverless computation, and network verification/repair/synthesis.
