Freshwater aquatic and/or riparian, hydrology in the western US. My research interests encompass environmental issues that affect the water cycle and water supply. I have worked on both shallow groundwater pollution issues and surface water processes that are related to climate variability and climate change. I have developed a type transfer function model (TTF) to assess pesticide leaching to groundwater at the regional scale. More recently I have worked on assessing streamflow timing changes across western North America. My current work is focused on the physical processes and characteristics of watersheds which are particularly sensitive to climate change, and on expanding my runoff timing assessments to other arid places in the world.
