General Information
I am a Project Leader in the Advanced Systems Division at the USC Information Sciences Institute.
I am also a Research Assistant Professor in the Computer Science Department at USC.
In Fall 2007 I taught a class on Grid Computing with Ann Chervenak in the Fall 07. More information about the class can be found at: http://vtcpc.isi.edu/CS599_GridComputing/index.php/CS599_Grid_Computing.
My main area of research is scientific workflow management in Grids. As part of this work I am leading the design and development of the Pegasus software that maps complex application workflows onto distributed resources. Pegasus is being used in a variety of scientific applications.
I am the co-Chair of the 3rd Workshop on Workflows in Support of Large-Scale Science (WORKS08), in conjunction with SC 08, Austin, TX, November 15, 2008 (deadline for submissions September 12, 2008).
In May 2006 I co-chaired the NSF-funded Workshop on Challenges of Scientific Workflows, http://vtcpc.isi.edu/wiki
I also co-edited the book “Workflows for e-Science,” to be published by Springer in December 2006.
I am also interested in large-scale data management issues, especially concerning metadata management. In particular, I am leading the design and development of the Metadata Catalog Service (MCS), a catalog that allows for the storing and querying of descriptive attributes associated with data objects such as files.
Before joining ISI in October of 2000, I was a Sr. Development Engineer in the Parallel Computing Laboratory at UCLA.
In 1997 I received a PhD in Computer Science from Rensselaer Polytechnic Institute. My work focused on "Optimizing Parallel Discrete Event Simulation for Spatially Explicit Problems"
