SIGMA: The Scientists' Intelligent Graphical Modeling Assistant Project

The goal of the SIGMA project is to develop software tools to assist scientists who are building scientific models. SIGMA is research and development effort within the Computational Sciences Division of the Information Systems Directorate at NASA Ames Research Center.

SIGMA is co-funded by NASA's Applied Information Systems Research Program, and NASA's Office of Space Access and Technology.

Dr. Richard Keller (keller@ptolemy.arc.nasa.gov) is the principal investigator on the project.
