My research focuses on the fate and transport of environmental contaminants in soil. I am currently studying how biochar (a carbon-rich material created by heating biomass in a low oxygen environment) influences the mobility and bioavailability of a variety of pesticides in soil. I am particularly interested in the sorption and desorption mechanisms of agrichemicals on biochars prepared from diverse feedstock materials.
