Research Interests
My research focuses on the aqueous biogeochemistry of sedimentary systems. I am particularly interested in the thermodynamics and kinetics of reactions that occur at interfaces between minerals and water, such as the adsorption of metals at mineral surfaces and rates of mineral dissolution, and in biogeochemical cycling, including oxidation-reduction pathways and kinetics, the role of microbial community structure in mediating redox reactions and the influence of macrofaunal and macrophyte activity on solute transport in sedimentary systems. In my research program, I seek to apply an integrated balance of field, laboratory and quantitative modeling methods to the questions that I address.
