Greg is a Hydrologist for the Wyoming-Montana Water Science Center focusing on water quality with a special interest in post-fire hydrology.
Greg attended Penn State in University Park, PA and worked as a technician for the USDA-ARS while completing his BSc. He assisted with collecting and analyzing soil, plant, and water samples originating from agricultural fields for various chemical and physical properties. He then attended Washington State University to complete his MSc. At WSU, Greg researched the impacts of frequent wildfires on soil-water-plant interactions on the southern face of Mount Adams in southwestern Washington State.

A call for strategic water-quality monitoring to advance assessment and prediction of wildfire impacts on water supplies
Wildfires pose a risk to water supplies in the western U.S. and many other parts of the world, due to the potential for degradation of water quality. However, a lack of adequate data hinders prediction and assessment of post-wildfire impacts and recovery. The dearth of such data is related to lack of funding for monitoring extreme events and the challenge of measuring the outsized hydrologic and eWater-quality, bed-sediment, and invertebrate tissue trace-element concentrations for tributaries in the Clark Fork Basin, Montana, October 2019–September 2020
Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana, as part of a monitoring program in the Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the Clark Fork Basin and monitor trace elements associated with historiWater-quality, bed-sediment, and invertebrate tissue trace-element concentrations for tributaries in the Clark Fork Basin, Montana, October 2018–September 2019
