PNNL

Heath Stanfield joined PNNL in 2023 as a summer Science Undergraduate Laboratory Intern through the Department of Energy Office of Science, working with Quin Miller and Todd Schaef in the Subsurface Science group. He then transitioned to a remote tech internship while finishing his final year at the University of Chicago. He returned to PNNL in the summer of 2024 as a post-bachelor’s research associate, working on projects related to the subsurface’s role in the clean energy transition. He works on a broad range of projects focused on geologic CO₂ storage via mineralization in mafic-ultramafic rocks, recovery of critical minerals, geologic hydrogen, and direct air capture.
