Investigations of soil inorganic chemical processes and soil mineralogical properties in relation to soil and environmental quality. Research interests include the use of pyrolysis to process biomass into bioenergy and biochar co-products, and the impact of biochar amendments on soil quality, the stability of biochar in soils, and the net impact of biochar on greenhouse gas emissions from soils. Other research interests include the chemical, mineralogical, and surface properties of soil clays, interactions of pesticides and other organic compounds with clays, the nature of soil humic substances, clay-humic interactions, and the development of field-mobile near infrared diffuse reflectance spectroscopy for mapping soil organic carbon and other properties.
