Sam Johnson

Dr. Samantha Johnson hails from eastern Colorado. She received her B.S. in Chemical Engineering from University of Colorado, Boulder in 2011. She received her Ph.D. in materials science from California Institute of Technology in 2017 where she was a National Science Foundation Graduate Fellow and a Resnick Fellow. She was a postdoctoral researcher in the Center for Molecular Electrocatalysis at Pacific Northwest National Laboratory. Dr. Johnson joined PNNL as staff in 2019. Her work at PNNL has focused on ammonia oxidation, hydrogen storage on liquid carriers, and solvation effects in mass spectrometry. In particular, she is interested in the role of a molecule’s surroundings in its performance and behavior. To study these effects, she uses a combination of electronic structure and molecular mechanics-based approaches.
