Dr. Xu’s research is on the interactions of computer systems and applications. It studies systems support for emergent applications and investigates novel ways of design and implementation of applications enabled by latest advance of systems.
- 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 on one hand 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. Recent work focused on resource management in cloud datacenters, edge computing infrastructure, and 5G-enabled IoT systems including self-driving vehicles.
- On the other hand, Dr. Xu’s research looks into smart city applications and intelligent transportation, in particular, and develops autonomous, pervasive, privacy-preserving technologies for data analytics and data-driven intelligence. Recent emphasis is on automatic machine learning, and deep federated reinforcement learning for smart city and autonomous driving.
Dr. Xu’s research team is comprised of an elite group of students and research associates, who actually conduct the nuts and bolts of the research. Most of his former PhD students and post-docs have escaped to academic positions or major industrial labs. For information about current research team, please refer to State Key Laboratory of Internet of Things for Smart City and Center for Cloud Computing for details. Dr. Xu continuously looks for self-motivated and hard-working students to join force. Financial support is available for those who have demonstrated a passion for their work.
