- Dr. Xu delivered a keynote speech on "Cloud Computing and Autonomic Management" to WoGTA'08 conference in Taiwan in December 2008.
As computer systems become more and more networked and complex, new
foundations are needed for understanding and controlling their integral
properties. Dr. Xu's research is dedicated to the investigation,
establishment, and experimental evaluation of new theoretical foundations
and system artifacts to significantly improve the systems performance,
availability, security, and energy efficiency.
