Patrick Drohan
Research Summary
Examines people’s use of landscapes and the accompanying changes in soil function across the larger ecosystem the soil supports and how this new knowledge can be used in applied research to improve land management and ecosystem stability. Current research addresses changes in dynamic and inherent soil properties across time scales spanning the Pleistocene to present.
