About Us

Dr. Bhatia leads the Grid Middleware Development Group at the San Diego Supercomputer Center, a research unit of the University of California San Diego. Dr. Bhatia specializes in grid computing, peer-to-peer computing, service-oriented architectures and other aspects of wide-area distributed computing. Dr. Bhatia received a PhD. from UCSD in the area of fault tolerance in wide-area computing and prior to his current position, he worked as a senior engineer at Entropia a desktop grid-computing vendor.

Kate is a programmer and deployment manager of the Inca software and has worked in SDSC's Grid Development group since July 2004. She contributes to Inca's design, installation and management for large, multi-site Grids and tasks in scientific areas related to advanced computing and networking. Most of Kate's work is related to deploying Inca on the TeraGrid and providing user support for Inca production software.

Sriram joined the Grid Development Group at SDSC in Oct 2004 to work on Web and Grid services middleware for scientific applications. He is the primary architect and developer of the Web services based infrastructure for biomedical applications funded by the National Biomedical Computational Resource (NBCR) at UCSD. This work includes the Opal Toolkit for wrapping scientific applications on the Grid as Web services. Since 2006, he is also working on a similar infrastructure for the CAMERA project, catering to the needs of the metagenomics community. Sriram is also an active participant of the Gemstone project at SDSC.

Prior to this, Sriram was a graduate student at the Computer Science department at Indiana University from 1999 to 2004 where he obtained his Ph.D. degree. His thesis was titled - An Architecture for Checkpointing and Migration of Distributed Components on the Grid. His expertise is generally in the area of Grid systems. In particular, he is proficient in Web service and Component technologies, and Grid middleware.

Steve joined the San Diego Supercomputer Center in 1998. While he started out writing parallel applications, he quickly moved into the emerging area of Grid software, and in particular Grid Portals. Steve worked on both the Hotpage and Gridport projects before moving on to work on several projects in scientific workflow. From there he spent some time working within Service Oriented Architectures developing web services and XUL applications for the SDSC Gemstone project.

Steve is now involved with the Teragrid Project's gateways effort to improve the development environment through the development and documentation of web services on the Teragrid resources.

Shava joined the San Diego Supercomputer Center in October 2002 and is currently lead developer of Inca. Inca is a system that provides user-level monitoring of Grid functionality and performance and has been running on TeraGrid since 2003. Prior to this position, Shava worked on Grid portals in the Extreme! Computing Lab at Indiana University. Shava received her B.S. and M.S. in computer science from UCSD. For her thesis, she developed a dynamic scheduler for an on-line parallel tomography Grid application being used by National Center for Microscopy and Imaging Research.

Sandeep joined SDSC in August 2003 and has worked as the lead systems developer for the GEON(GEOsciences Network) project. His responsibilities include establishing, deploying and administrating the distributed grid and cluster framework and developing middleware grid solutions. He is also responsible for managing the CyLab (A collaborative middleware testbed between SDSC and NCSA) testbed at SDSC.

Sandeep has recently taken up a different role. He is now working as the Technical Project Manager for the TEAM cyberinfrastructure project.

Prior to joining SDSC, Sandeep was working for the Advanced Software Engineering Research group at Oak Ridge National Labs, Tennessee. He graduated with a Master of Science in Computer Science degree from North Carolina State University (The Wolfpack) in 2002.

Dr. Kaiser joined the Scientific Computing Services group at SDSC in January of 1998. Tim has been director of training and manager of the Parallel Tools Group. He is currently working with a geoscience group enabling large scale earthquake simulations from a web portal. He is responsible for the actual running of the earthquake simulation as well as pre and post processing. He has added numerous enhancements to the simulation, including new boundary conditions and MPI output. He has also developed a Python MPI module that is being used by numerous groups wishing to merge Python and HPC. The module is compatible with C and Fortran and includes support for MPI-2 dynamic process management. Dr. Kaiser is currently studying the use of MPI-2 dynamic process management to enable more fault tolerant applications. He is also helping the NBCR project improve the performance of a number of biological applications.

Kurt has been working with Grid software since joining SDSC in 2000. He is the primary developer of GAMA, a system for creating and managing Grid user accounts. He has also worked extensively on the CAMERA project, principally on the Single Sign On security architecture and on portlets for BLAST and other scientific applications. Kurt has extensive experience with the GridSphere portlet framework.

Prior to working on GAMA, Kurt was involved with early Grid computing projects including the GridPort toolkit and the NPACI HotPage.

Brent has been in the Grid Development Group since 2003 and is the lead developer for the Gemstone project
