Alexandru Iosup is currently with the Parallel and Distributed Systems group, TU Delft, NL, following a doctoral track in Computer Science. Before this, he has received in 2004 a M.Sc. degree from the Politehnica University of Bucharest, Romania, and a Werner von Siemens Award, for the same work. In the fall of 2006 he was a visiting researcher with the Condor group, U.Wisconsin-Madison. His research interests are in the areas of parallel and distributed computing, with a focus on grid and peer-to-peer systems (keywords: resource management, scheduling, performance evaluation, workload characterization). He is the co-founder of the Grid Workloads Archive, the largest archive for workload traces from grid computing environments. He is a member of the team that performed the largest BitTorrent measurements and analysis to date; he received the IEEE P2P best-paper award for improvements to the same peer-to-peer network. He is currently working on resource management for large-scale distributed computing systems and for massively multiplayer online games. He is a member of the ACM, IEEE, IEEE Computer Society, and IGDA.
