Our research spans both scientific and engineering aspects of groundwater resources. Investigations typically involve field sites and focus on topics ranging from the analysis of environmental remediation schemes to the study of paleoclimate and paleohydrology. The scales of physical processes of concern extend from the domain of small pores to vast regional subsurface flow systems. In all of our work, we develop conceptual and quantitative predictive models. Such models enhance our understanding of groundwater flow behavior and provide means for resource evaluation and management.
