Research Interests
My research investigates the fate and transport of contaminants in groundwater, air, and soil, with particular emphasis on human health and exposure risks in urban environments.

Two overarching themes connect my research.  The first involves the
innovative application of deterministic and stochastic methods to describe spatial variability of physical and chemical characteristics of environmental systems.  The second involves the assessment of alternative conceptual models to describe states and processes in those same systems.  I am intensely curious about how decisions concerning the representation of spatial variability and the application of alternative conceptual models influence the outcomes of numerical models of natural and engineered systems. More importantly, I have come to appreciate the influence of environmental models on assessments of risks associated with exposures to environmental contaminants.  Questions involving the development and application of spatially and temporally variable environmental models have important practical implications for decision makers seeking to minimize risks and costs associated with environmental hazards and for policy makers seeking to optimize health outcomes associated with potential environmental exposure risks.​
