The Integrated Data Frameworks (IDF) group performs research and development on software and methodology for improving the security, quality, and usability of analysis tools for scientific and applied data. The group is a mix of software engineers and computer scientists. We work with earth scientists, material scientists, chemists, process engineers, and physicists, as well as the NERSC and ESNet facilities. Our approach is distinguished by a strong focus on usability and user research, early and often in the software design process. We have learned that designing the best systems can only occur when we have the best understanding of the constraints, needs, and culture of the scientists who will use it. The IDF group works closely with the Usable Software Systems group on research and development of user-centered solutions.
