Tadmor and Elliott receive $2 million NSF Grant

This simulation of cracking in copper was noteworty for being the first to break the "1 billion atom" barrier and studying a sample of material approaching macroscopic lengthscales.

Proceedings of the National Academy of the United States of America (PNAS), vol 99, pp. 5777-5782 (2002).

Prof. Ellad Tadmor and Assistant Prof. Ryan Elliott (AEM), together with Prof. Jim Sethna at Cornell University, have been awarded a four year $2 million grant by the National Science Foundation (NSF) to create a tool that will equip scientists across their field with information that is aimed to ultimately revolutionize their research.

The group is chartered to create a Knowledge-base of Interatomic Models (KIM), an "interactive, self-extending, database of interatomic models, self-contained simulation codes that test the predictions of these models, and reference data." The project also involves establishment of standards for the field in collaboration with NIST. In addition to the PIs, the project includes close collaboration with Prof. Ronald Miller (Carleton University, Canada), Dr. Chandler Becker (NIST) and other key players at national labs, industry and other universities in the U.S. and abroad. The KIM project is part of the NSF's Cyber-enabled Discovery and Innovation (CDI) program.

From the NSF Website: "This project aims to answer the question: When and to what extent can we believe the results of atomistic simulations of materials? The project's objectives are of central concern to an unusually large cross-section of the industrial and scientific communities who are interested in understanding materials from their basic building blocks; this includes physicists, materials scientists, chemists, and engineers from academia, government, and industry...."

The PIs would like to acknowledge Dr. Anne-Francoise Lamblin for her critical reviews of the research narrative and valuable comments regarding informatics and data management plan. Dr. Lamblin is a bioinformatics scientist and the Coordinator for the University of Minnesota Interdisciplinary Informatics in the Office of the Vice President for Research.
