Dantong Yu

Group Leader

Dantong Yu joined Brookhaven National Lab in 2001, and coordinated the Grid computing group at BNL. He currently leads the computer science group at the Computational Science Center. His research interests include high-speed network performance, network qualify of service, cluster/grid Computing, information retrieval, data mining, database, and data warehouse. He designed and implemented a novel high-dimensional indexing algorithm (termed ClusterTree) using the semantics of datasets. He has published papers in leading technical journal and conferences. He initiated and led the high performance network provision effort to bring cutting-edge network technologies into the big data management for science applications. He served in the review Panels of NSF CDI, DOE Early Career Principle Investigator for networking research and DOE Small Business Innovative Research (SBIR) and co-chair of several DOE Advanced Networking Workshops for Distributed Petascale Science.
