Dr. Philip J. Rhodes joined the faculty in 2004 after receiving his Ph.D. from the University of New Hampshire. He is chief architect and implementer of the Granite system, a library that provides efficient and convenient access to spatial datasets such as those produced by two and three dimensional simulations. At the graduate level, Rhodes teaches on scientific data representation and analysis, scientific visualization, computer graphics, and cloud and parallel computing.
Dr. Rhodes’s research focuses on the unique problems presented by spatial data and computation. Grid and Cloud computing have been a subject of intense interest in recent years, and his recent research addresses the notoriously difficult problem of providing efficient access to spatial datasets stored in far away locations. He has developed visualization methods that avoid disk and network latency costs, vastly improving performance and the size of feasible visualizations.
Other work performs automatic partitioning of spatial datasets among nodes in a cluster, using advance knowledge of the computation access pattern to optimize performance. Recent work also includes investigation of efficient spatial data access methods for GPU computing environments.
