Dr. David A. Cullen is a Senior R&D Staff member in the Materials MicroAnalysis Group at the Center for Nanophase Materials Sciences. He received a B.S. in Applied Physics from Brigham Young University, and a Ph.D. in Materials Science and Engineering from Arizona State University, after which he joined Oak Ridge National Laboratory in 2010 as an Alvin M. Weinberg Fellow. He is a prolific, impactful author with an extensive list of national and international collaborations established through projects funded by EERE’s Hydrogen and Fuel Cell Technologies Office (HFTO) and the Center for Nanophase Materials Sciences, which is a DOE Office of Science User Facility. His current research is focused on efforts in three HFTO consortia -- H2NEW, M2FCT, and ElectroCat 2.0 -- which aim to deliver sustainable hydrogen production through water electrolysis, durable fuel cells for heavy duty vehicles, and low-cost oxygen evolution and reduction catalysts. In 2019, he received the Presidential Early Career Award for Scientists and Engineers (PECASE) in recognition of his groundbreaking scientific accomplishments in correlating the atomic structure and chemistry of fuel cell materials with durability and performance using advanced, analytical aberration-corrected scanning transmission electron microscopy.
