Specialty: Soil and Environmental Hydrogeochemistry
The overarching goal of our research program is to help better predict, manage and respond to environmental contaminants that threaten human health. Contaminant distributions in soils, sediments and natural waters are controlled by a host of physical, chemical and biological processes, each of which can exert its influence over a range of spatial and temporal scales. In our research, we integrate a suite of field, laboratory and spectroscopic approaches to better understand the sources, fate and transport of contaminants in the environment. Research themes include 1) aquifer vulnerability to contamination; 2) agricultural impacts on trace-element distributions in soils, surface water and groundwater; and 3) water quality and sanitation in low-income countries.
