Dr. Xubin He is a professor in the Department of Computer and Information Sciences at Temple University.  He has been conducting extensive research in the area of data storage and I/O systems. His research interests include networked storage, big data management, storage cache and disk I/O, high availability and reliable computing. Dr. He's research has been mainly sponsored by the U.S. National Science Foundation (NSF). He has authored and co-authored many technical articles in prestigious journals such as IEEE Transactions on Parallel and Distributed Systems (TPDS), Journal of Parallel and Distributed Computing (JPDC), ACM Transactions on Storage (ToS), and IEEE Transactions on Dependable and Secure Computing (TDSC), and at international conferences, including the USENIX Conference on File and Storage Technologies (FAST), EuroSys, USENIX Annual Technical Conference (ATC), ACM International Conference on Supercomputing (ICS), IEEE/IFIP International Conference on Dependable Systems and Networks (DSN), IEEE International Parallel and Distributed Processing Symposium (IPDPS), IEEE International Conference on Local Area Networks (LCN), etc. Graduate students who have graduated under Dr. He's supervision usually work in computer industry or research institutions as computer engineers or design architects. Dr. He has served as a panelist for NSF, also as a general/program chair and a technical committee member for many professional conferences in the field. He received the Ralph E. Powe Junior Faculty Enhancement Award in 2004 and the Sigma Xi Research Award (TTU Chapter) in 2010 and 2005. He is a senior member of the IEEE, a member of the IEEE Computer Society and USENIX.
