Welcome to the Asta Group

We leverage state-of-the-art computational techniques and resources to study advanced materials for the next generation of engineering technologies. Our current research area focuses include advanced structural alloys, functional semiconductors, Generation IV nuclear reactor materials, and code development. We are located in the Department of Materials Science and Engineering at the University of California, Berkeley.
