Prof. Scott Brandt is Associate Professor of Computer Science, the UCSC Director of the ISSDM and the Director of Graduate Studies for the Computer Science Department at the University of California Santa Cruz. He is also Director of the UCSC Real-Time Systems Laboratory, Associate Director and co- founder of the UCSC Storage Systems Research Center, and co-founder UCSC/Los Alamos Institute for Scalable Scientific Data Management. Scott's research is in the area of Computer Systems. He specializes in both storage systems and real-time systems. His current storage system research focuses on high-performance peta-scale distributed object-based storage, while his real-time research focuses on integrating real-time and non-real-time processing into a uniform processing environment. His most recent research intregrates the two, researching novel solutions for robust guaranteeable management of varied system resources, including CPU, disk, memory, and network.
