[01-06-2020] Our research projects on big data and IoT are featured in CIS news letter.
[08-26-2019] Welcome new PhD student Peiyu Liang to join our lab!
[12-11-2018] Our paper "GearDB: A GC-free Key-Value Store on HM-SMR Drives with Gear Compaction" has been accepted for presentation at the USENIX Conf. on File and Storage Technologies (FAST'2019), acceptance rate: 26/145=18%. USENIX FAST is a premier conference in data storage systems.
[06-22-2018] NSF CCF Award: 2018-2021, $460k. Our NSF proposal "SHF:Small: Collaborative Research: Understanding, Modeling, and System Support for HPC Data Reduction" was selected for funding.The goal of this project is to address a number of critical gaps in using data reduction for HPC-based science missions. This is a collaborative project with NJIT.
[04-30-2018] Yuhua (co-supervised with Dr. Weijun Xiao@VCU) successfully defended his dissertation. He is going to join DataDirect Networks (DDN). Congratulations, Dr. Guo!
[04-18-2018] Our paper "RAFI: Risk-Aware Failure Identification to Improve the RAS in Erasure-coded Data Centers" has been accepted for presentation at the 2018 USENIX Annual Technical Conference (ATC'2018), acceptance rate: 76/378=20%. This is a joint work with collaborators at HUST. USENIX ATC is a premier conference in computer systems.
[[January 2018] Congratulations to Ting and Wenjie who both received USENIX travel grants to attend the FAST'18 conference.

Dr. Xubin 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 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. Dr. 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. Graduate students who have graduated under his 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, ACM, and USENIX. Prior to joining Temple, he was a faculty member at VCU (2010-2016) and Tennessee Tech University (2002-2010).
