Co-Director of the Environmental Sciences Graduate Program
My research program focuses on environmental soil chemistry
Fundamental biogeochemical processes that affect heavy metal and trace element bioavailability, human health, and ecological risk in soil-water systems
Development of innovative chemical methods and techniques to evaluate soil chemical processes and soil components that control bioavailability and/or risk of chemical species (e.g., nutrients, contaminants)
Risk-based environmental chemistry of organic and inorganic pollutants in contaminated soils with emphasis on human (e.g., public health), agronomic (e.g., crop, animal), and ecotoxicity bioavailability and contaminant transmission pathways
Development and evaluation of new technologies used for remediation of contaminated soils (e.g., in situ immobilization, bioremediation)
Development of innovative in vitro chemical methods to evaluate the ability of new remediation methods to reduce contaminant bioavailability and risk and to evaluate the long-term environmental fate (e.g., longevity) of remediation
Beneficial use of agricultural, industrial, and municipal by-products through land application
Soil and environmental chemistries of by-products in agronomic/environmental systems with emphasis on their risk and environmental impact
