Andrew L. Masterson, Ph.D.

Andrew Masterson is a Research Chemist with the USGS Energy Resources Program’s Oil and Gas Waters project and the Mineral Resources Program’s Sulfur Cycle and Sulfide-hosted Critical Minerals project. His research conducts investigations related to the geochemical origin and assessment of lithium and elemental commodities in produced waters and brines, including those derived from the Smackover Formation in the Gulf Coast basin, experiments aimed at improving traditional and non-traditional isotope proxies for characterizing basinal fluid flow, and generating laboratory analogues of microbially-enhanced weathering of sulfide-hosted critical minerals. His research additionally includes development of laboratory reference materials and method development in assessing the high temperature interaction of brines and silicate minerals in the Oil and Gas Waters BRInE Laboratory.
