Traditionally, redundancy and error tolerance capability are considered the key performance measures for ECC. In distributed storage, however, codes need to be developed for the new challenges brought by the networked nature of the system. In this talk, we present regenerating codes, a family of codes that are efficient for failure correction.  For systems with 2 redundant storage devices, the repair bandwidth can be reduced by 1/2 compared to traditional ECC.   Speaker Biography: Zhiying Wang is an Assistant Professor at University of California, Irvine. She was a postdoctoral research fellow at Stanford University. She received Ph.D. and M.S. in Electrical Engineering at California Institute of Technology, and B.S. in Information and Electronic Engineering at Tsinghua University. Her research interests include information theory, coding for data storage, and compression for genomic information. She is the recipient of IEEE data storage best paper award and NSF Center for Science of Information Postdoctoral Fellowship.   Questions:   Dr. Lan Nguyen IEEE OC ComSig Chapter Chair lan.nguyen@linquest.com
