Dr. Brett A. Helms is Staff Scientist at the Molecular Foundry, Lawrence Berkeley National Laboratory. His research program at LBNL is devoted to understanding architecture–property relationships in micro- and meso-structured materials. He and his research group harness synthetic chemistry, computational insights, X-ray characterization, and engineering to forge a molecular-level understanding of materials to realize performance advantages with them in EUV photoresists, batteries, adaptive and reconfigurable energy materials, and chemically recyclable polymers for the circular economy. Prior to beginning his independent career, he completed his PhD in Chemistry at the University of California, Berkeley under the direction of Prof. Jean M. J. Fréchet (co-inventor of chemically amplified photoresists) and postdoctoral work at the Technische Universiteit Eindhoven with E. (Bert) W. Meijer.
