Geoff began working with the UWEX state soil specialists at UW Madison in early 2014 as an outreach specialist. His research to date has focused on contaminant behavior and impacts in soil, sediment and water with a strong emphasis on stakeholder driven projects at the interface of science and policy. Currently he is working on projects involving soil lead in urban and rural areas, developing statewide anthropogenic polycyclic aromatic hydrocarbon baseline values, and soil denitrification of cheese making and vegetable processing wastewater. In addition, Geoff currently serves on the WI Brownfield Study Group, the advisory body for state remediation and redevelopment practices on contaminated sites.
