Randall J Hunt, Ph.D.
Randall Hunt is a Chief Science Officer with the Upper Midwest Water Science Center.
AREAS OF EXPERTISE
My work focuses on water flow, and its effect on natural systems. This research uses a variety of approaches such as numerical modeling, ion and isotope chemistry, tracers, parameter estimation, and stochastic methods. It emphasizes a range of groundwater – surface water systems including wetland, stream, and lake interactions. More recently this work has been extended to research investigating ecohydrology of aquatic systems, effects of climate and landuse drivers, and source and transport of enteric viruses to drinking water wells and temperature through watersheds. Much of my work has focused on improving model forecasts and uncertainty estimates for decision making.
