Research Interests
Research interests relate to the physical, chemical, and biological processes that govern the transport and transformation of pollutants in the environment and their application toward the remediation of contaminated systems. Areas of current emphasis include laboratory and field experiments as well as mathematical simulations of biogeochemical processes in porous media, such as: (1) numerical simulation of denitrification in soils as a function of rainfall and soil properties, and the scaling of these results to link them to climate change models; (2) biogeochemically mediated dynamics of trace metals in sediments, wetland soils, and groundwater; (3) biological reduction of uranium in groundwater and the long-term stability of the reduced uranium phases; (4) nitrogen processing in urban settings coupled to urban hydrology; and (5) effects of carbon dioxide sequestration in deep aquifers on shallow soils due to potential leaks. Professor Jaffe has served on numerous committees and panels, including the National Research Council, EPA, NIH, and DOE.
