Trishelle Copeland-Johnson is a Materials Research Scientist at Idaho National Laboratory with a background in chemical engineering. Her expertise is using multi-modal advanced characterization techniques to elucidate synergistic effects, such as structural phase transformations, fission products, and irradiation, on the corrosion mechanism of structural materials for advanced nuclear reactors. Dr. Copeland-Johnson arrived at INL as a Glenn T. Seaborg Distinguished Postdoctoral Research Associate in 2021, investigating the role of actinide products on the corrosion mechanisms of Ni-based superalloys in chloride molten salts and the synergistic effects of gamma irradiation and radiolysis on the evolution of surface corrosion products on aluminum spent nuclear fuel cladding alloys. Dr. Copeland-Johnson leads an INL laboratory-based research and development initiative to elucidate the role of long-range ordering phase transformations on the corrosion mechanism of Ni-based alloys in molten salts. She is also co-PI on a project funded by the Department of Energy Office of Basic Energy Sciences, leading groundbreaking efforts to investigate the impact iodide fission products on the corrosion mechanism of Ni-based alloys in chloride molten salts. She has presented 7 invited talks, 4 conference presentations, and published 5 peer-reviewed articles, featured in Corrosion Science and the 2022 Frontiers in Nuclear Engineering, Rising Stars in Nuclear Materials special issue.

Dr. Copeland-Johnson also has an extensive record of professional development and outreach activities. She has served as the chair and vice-chair for the User Executive Committee for the BNL Center for Functional Nanomaterials, a Department of Energy Nanoscale Science Research Center. Also, she is a stanch supporter of enhancing the workforce development pipeline for underrepresented ethnicities in science and engineering disciplines through professional organizations, such the National Organization for the Advancement of Black Chemists and Chemical Engineers (NOBCChE) and the Minerals, Metals, & Materials Society (TMS). She was also awarded the 2022 INL Materials and Fuels Complex Mentor of the Year.
