Trent R. Graham joined Pacific Northwest National Laboratory (PNNL) in 2017 for the final year of his PhD candidacy at Washington State University (WSU) as an independently funded research fellow through the PNNL-WSU Distinguished Graduate Research Program. After receiving his PhD in chemical engineering, he continued to perform research at PNNL as a chemical engineer in the geochemistry group. At PNNL, he conducts orthogonal research techniques to investigate the molecular-scale structure, dynamics, and reactivity of solvated oxyanions pertinent to nuclear waste.
