Bio

My expertise is in economic geology, geochemistry, and geologic mapping, with a focus on metallic mineral deposits. My research integrates micron to map scale observations to understand geologic systems. Before joining AZGS, I spent five years at the Wisconsin Geological and Natural History Survey conducting geologic mapping and studying Mississippi Valley-Type sulfide deposits in southern Wisconsin, with an emphasis on their groundwater quality impacts and critical mineral potential.
