Cyrus D Harrison
Cyrus is a computer scientist and group leader in the Applications, Simulations, and Quality (ASQ) division of LLNL's Computation directorate. He is the software architect of the VisIt open source visualization tool and leads major aspects of the technical direction of the project. Cyrus also provides custom data analysis solutions for large scale scientific simulations in WCI's WSC and WPD programs.
Cyrus obtained a B.S. (2003) and Masters (2004) of Computer Engineering from the University of Florida. He joined LLNL in February 2005.
