I am a Ph.D. Candidate (6th year) in the Distributed Systems Laboratory in the Computer Science Department at University of Chicago in Chicago, Illinois. My research advisor is Dr. Ian Foster and my main area of research is Grid Computing, with an emphasis on resource management in large scale distributed systems and grid computing. Within resource management, I am particularly interested in efficient task dispatch and execution systems, resource provisioning, data management, scheduling, and performance evaluations. My latest work revolves around a system called Falkon, which I designed and implemented, to enable the rapid and efficient execution of many independent jobs on large compute clusters. Falkon combines three techniques to achieve this goal: (1) multi-level scheduling techniques to enable separate treatments of resource provisioning and the dispatch of user tasks to those resources; (2) a streamlined task dispatcher able to achieve order-of-magnitude higher task dispatch rates than conventional schedulers; and (3) performs data caching and uses a data-aware scheduler to leverage the co-located computational and storage resources to minimize the use of shared storage infrastructure. I am also interested in Parallel Computing, Networking, Peer-to-Peer Networks, and Wireless Sensor Networks. My work has been supported in part by the NASA Ames Research Center GSRP Grant Number NNA06CB89H and by the Mathematical, Information, and Computational Sciences Division subprogram of the Office of Advanced Scientific Computing Research, Office of Science, U.S. Dept. of Energy, under Contract DE-AC02-06CH11357.
