Areas of Research Interests/ Research Projects

Parallel and Distributed Systems

Storage System

National Basic Research Program of China (The 973 Program): Research on Structure-Independent Disaster Recovery Techniques and Implementations (2007-2011).

Research Status

My research interests are parallel, distributed, and storage systems. I have carried out one of the first measurement studies of large VOD systems, and indicated user behavior and content access patterns of such systems, and their implications in designing multimedia streaming systems. I have also developed a new data protection and recovery system based on OS virtualization techniques, which can instantly restore the interrupted services to a normal running state after disasters without the support of expensive hot standby solutions.

Honors And Awards

National Science and Technology Progress Award, Second Class-High-Performance Cluster Computers and Large-Scale Storage Systems (2007);

Science and Technology Progress Award by Ministry of Education, First Class-Whole-Process Evaluation Techniques and Applications of High-Performance Computing Systems (2009).
