Systems (Operating Systems, Networking, Storage, Databases)

Research in computer systems at The University of Arizona spans system design and development in providing computational needs of the emerging big data challenges from astronomy to healthcare.  To provide future systems with needed capabilities and higher performance we are making advances in databases (Snodgrass), distributed systems (Gniady, Hartman, Snodgrass, Zhang), energy efficiency (Gniady, Zhang), networking (Zhang), operating systems (Gniady, Hartman), and storage systems (Hartman).

Our research emphasizes developing innovative software systems.We’re investigating integrating both hardware and software mechanisms for overall improvement in system performance and energy efficiency, evolving from today's host-centric network architecture IP to a data-centric network architecture (NDN), providing cloud access to the largest publicly available contiguous dataset available in genomics, the limits of conventional cost-based query optimization, and a fundamentally new approach the achieving better DBMS performance. We are also applying novel solutions for medicine and civil engineering to provide improved communication and data reliability by advanced operating system and networking technologies.

Our collaborations involve colleagues in the College of Medicine, the College of Engineering, and the National Optical Astronomy Observatory (NOAO) located on campus.
