Peggy Li

Biographical Sketch

P. Peggy Li reeived a BS and an MS in electrical engineering from the National Taiwan University, Taiwan, and a PhD in computer science from the California Institute of Technology in 1986. She was the technical group supervisor for the Parallel and Distributed Application Technology Group (formally Automation and Scheduling Technology) in the Applications Development Section from 1996 to 1999. She led many research and development tasks in the parallel and distributed computing area since she joined JPL in 1989, including the development of a distributed discrete event simulation framework, and a remote interactive visualization and analysis (RIVA) system for the planetary data visualization. She is currently leading development of regridding components for the Earth system modeling framework. Also, she manages development of several data portals for oceanographic data. Her research interests include scientific visualization, parallel rendering, and distributed computing.

Projects

• Ocean data portals
• Earth system modeling framework development, especially regridding
