Our group has investigated all aspects of water-rock-biota interaction throughout the critical zone – the entire zone extending from the top of vegetation to groundwater. We have developed models for soil formation on rocks of different composition under different conditions. Our work also includes studies of the impacts of human activities such as shale-gas development on water quality, and how to work with the public on concerns related to hydraulic fracturing.
