General Information

I am a Project Leader in the Advanced Systems Division at the USC Information Sciences Institute.

I am also a Research Associate 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://confluence.pegasus.isi.edu/display/CS599/Home

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 4th Workshop on Workflows in Support of Large-Scale Science (WORKS09), in conjunction with SC 09, Portland, OR, November 16, 2009

In May 2006 I co-chaired the NSF-funded Workshop on Challenges of Scientific Workflows, http://confluence.pegasus.isi.edu/display/workshop06/Home

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"
