Ph.D., Computer Science, August 2000, Univ. of Virginia, Charlottesville, VA.
Topic: Integrating Fault Tolerance in Grid Applications

M.C.S., Computer Science, July 1995, Univ. of Virginia, Charlottesville, VA.
Topic: The Mentat Assistant Debugger: Post-mortem Debugging.
B.S.,
Magna Cum Laude, Computer Science, Physics, December 1992, The College of
William & Mary, Williamsburg, VA.


Experience
Research Manager, September 2003-current, University of Virginia, Charlottesville, VA.
• CoPI on two highly competitive grants: Dependable Grids (NSF ITR),
Genesis: a Framework for Achieving Component Diversity (DARPA Self-
Regenerative Systems program).
• Leveraged industrial contacts to initiate collaboration with major vendors
(IBM, Symantec Research).
• Designed strategy for research program direction. Led effort to promote
research group awareness in the community.
• Managed undergraduate student thesis.

Senior Software Architect, June 2000-August 2003, Avaki Corp., Charlottesville VA.
• Senior member of engineering team, oversaw transition from academic project
to robust, commercial offering.
• Led engineering in developing applications highlighting the strengths of
Avaki’s software platform for presentation to venture capital firms. First round
of funding ($6M) was awarded in 2001.
• Co-authored and presented Avaki’s Simple Grid Naming Protocol (SGNP)
draft specification at the Global Grid Forum 2002.
• Managed, designed and co-implemented development of web portal for
executing and monitoring grid applications.
• Designed and implemented failover capabilities to increase availability of
Avaki’s grid product.
• Increased reliability of Avaki’s products via heterogeneous, automated testing.



Chief Architect, June 1999-August 2000, Earth Music Network.
• Designed 3-tiered web architecture for Earth Music Network, a Hindi film music
site. The web site receives 1500+ hits a day (more than one per minute), and
continues to exist as one of the most popular sites on the web for searching for
Hindi music.
Doctoral studies, 1993-2000, University of Virginia
• Developed first architectural framework for composing fault-tolerance
techniques with grid applications transparently.
• Developed fault-tolerant, self-load-balancing architecture for bag-of-tasks
applications. Demonstrated reliability and performance with DNA/protein
sequence comparison applications.
• Architected implementation model for the Legion grid system. Primary
objective was to achieve extensibility to easily incorporate functionality such
as security, accounting, auditing, monitoring and fault-tolerance in
applications. All Legion objects were built based on this model.

Software Developer, 1991-1993, Thomas Jefferson National Laboratory, Department of
Energy, Accelerator Controls group.
• Developed user-interface for monitoring hardware devices.
• Developed 3D rendering software for visualizing electron beam.


Development
• Industry expert on compute-grid and data-grid systems
Experience
• C/C++, Java/J2EE
• PHP, Unix scripts (bash, ksh)
• log4j, Javadoc, JUnit for application-level logging, documentation, application
testing
• SQL
• JBoss and Tomcat for application deployment
• Perforce and CVS for source control
• TestTrack for bug tracking
• Ant and make for project development
• Parallel and Distributed Systems, Message Passing Interface (MPI), Parallel
Virtual Machine (PVM).
