I hold a joint appointment as an assistant computer scientist in the Mathematics and Computer Science (MCS) Division at the Argonne National Laboratory (ANL), and as a fellow of the Computation Institute at the University of Chicago. My areas of research interest include Parallel Programming Models, High-speed Networking Systems, Parallel and Distributed Computing, Job Scheduling and Resource Management and the general areas of Cluster and Grid Computing. More specific research projects can be found below. The information on this website is getting outdated quickly, so please see my CV below for more up-to-date information.
