Bachelor of Computer Science, Jilin University, Changchun, China, 2000;
Master of Computer Science, Jilin University, Changchun, China, 2003;
Ph.D. in Computer Science, Tsinghua University, Beijing, China, 2008.
Department of Computer Science and Technology at Tsinghua University: Director of Graduate Management Committee (2008-2010).
Areas of Research Interests/ Research Projects
Large-scale Storage Systems;
The National Natural Science Foundation of China:Efficient RAID Scaling in Network Storage (2010-2012);
The National High-Tech R&D Program of China (The 863 Program): Development and Application of PB-scale High-performance Mass Storage Systems (2009-2010).
As a principal investigator or a key technical personnel, I have taken part in multiple NSF, 863, or 973 projects.
I investigated the online scaling of RAID, found the reordering window characteristic in scaling a RAID volume. As a consequence, I proposed a series of efficient approaches to scaling RAID volumes, which improved the RAID scalability.
I have published 8 papers in journals or conferences. Among of them, one was published in ACM Transactions on Storage, and two were published in IEEE Transactions on Computers.
