Lyndsay B Ball
Lyndsay is a Research Geophysicist at the Geology, Geophysics, and Geochemistry Science Center in Denver, Colorado.
Her research explores hydrogeologic systems and subsurface processes using integrated hydrological and geophysical approaches, with an emphasis on electrical, electromagnetic, and airborne geophysical methods. Her current projects focus on the characterization of groundwater salinity and geologic controls on groundwater flow in mountain and intermountain settings.
