PNNL

Judy Robinson is a computational scientist with field and numerical modeling experience in geophysical methods, specializing in electrical resistivity imaging. Since joining PNNL in 2018, her work has focused primarily on joint inversion using flow and transport models with electrical resistivity imaging to determine the feasibility of field electrical imaging. She also has expertise in analyzing complex resistivity data and is working towards joint physical and geochemical interpretations using corroborating field and lab datasets.
