Biography

Ertem Tuncel received his Ph.D. in Electrical & Computer Engineering at University of California, Santa Barbara in 2002. Prior to joining the faculty at UC Riverside, he did postgraduate research at UC Santa Barbara, where he worked on various distributed source coding problems and content-based retrieval in multimedia databases. His current focus is on distributed source coding in sensor networks with emphasis on low-delay communication, multi-terminal joint source-channel coding, content-based retrieval from high-dimensional databases and fundamental limits of retrieval performance.
