Contaminant Hydrogeology: My research program is focused on evaluation of processes controlling the fate and transport of microbial and organic chemical pollutants in groundwater and development of remediation methods to address contaminated sites.
Determination of the distribution organic chemical between environmental phases (e.g. air, water, soil, etc.) and remedial phases (e.g. solubilization agents, sorbents, etc.).
Fate and transport of viruses and parasites in groundwater systems.
Evaluation of the fate and transport of pathogens and organic pollutants in stream/aquifer systems.
Development of treatment systems for hazardous waste sites and river water.
Research Philosophy: My research program is directed toward preserving and protecting the quality and quantity of water resources. This is one of the most important and exciting research areas of geosciences today. To contribute to that effort, my students and I evaluate the factors that govern the circulation of water and the transport, fate, and remediation of waterborne microbial pathogens and chemicals in subsurface and surface environments. In this pursuit, we integrate elements of hydrology, geology, microbiology, chemistry, mathematics, physics, and environmental engineering. Within the past couple of years my research has primarily focused on improving the efficacy of cyclodextrin, a cyclic sugar, as an agent for remediation hazardous waste sites. That has involved development of innovative theoretical models and collection of data on the phase distribution of organic chemicals as a function of environmental and engineering variables for cyclodextrin remediation systems. Due to the applied nature of my research, my students and I often must learn about public policy and finance, as well as plumbing, electrical wiring, and how to operate a drill rig while performing research, but also how to use a wide range of chemical and analytical instruments and computational models.
