Welcome to our Hydrogeology Research Group website!


Our group is interested in how different aspects affecting the hydrologic cycle – including the atmosphere, plants, soil, microbial activity, and geochemistry – interact with each other.  Understanding the links between these elements helps us explain how the environment will respond to changing conditions, including impacts of climate change, land use, and contamination.  I use computer models to describe dynamic connections at the land surface, in the unsaturated zone, and in groundwater aquifers.  My work also focuses on statistical methods that merge models with data (data assimilation) to provide more reliable and informative insights than is possible with either models or data alone.  


Our work has included: modeling of groundwater sulfate in northeast Minnesota, assessing the hydrology of tropical glaciated watersheds, investigating soil, crop, and climate controls on groundwater recharge in semi-arid areas of the High Plains; ecohydrological modeling of vegetation vulnerability and resilience in the Mojave Desert; assessing data assimilation methods for chaotic models of the atmosphere; and describing chemical, mineral, microbial, and transport processes that affect groundwater quality near Bemidji, MN and on Cape Cod, MA. 


Onngoing research combines integrated hydrological modeling and field observations to tackle problems in water resources, ecological sustainability, and biogeochemical cycling.  We are interested in arid to temperate settings, under both natural and human-impacted conditions.
