Professor, Department Head, Department of Soil Water and Environmental Science
Co-director, Arizona Laboratory for Emerging Contaminants (ALEC)
My research interests relate to biogeochemical processes occurring in soil, sediment and water. My lab group applies the tools of analytical chemistry - particularly mass spectrometry and molecular spectroscopy - in field, mesocosm and bench-scale experiments. An overarching goal is to elucidate coupled biological and geochemical processes that influence the form and mobility of metal(loid)s and organic molecules in the earth’s near-surface environment.
