(1) Application of Low-Temperature Geochemistry and Biogeochemistry in Environmental Contamination Problems:
Characterization and quantification of various physico-chemical processes that determine the behavior of inorganic and organic contaminants in soils and sediments; the relevant processes and the interrelationships among them over a wide range of spatial and temporal scales. Long-term goals are to develop understanding based on experimental and theoretical investigations, as well as to modify predictive capabilities of the expected system behavior, management, control and remediation technologies. Includes geochemical modeling and spectroscopic evaluation of processes at liquid-solid-biota interface.

(2) Application of Biogeochemistry in Waste Recycling and Nutrient Management in Soils:
Evaluation of field, greenhouse, and experimental data (macroscopic and microscopic) to investigate plant and human bioavailability, aqueous and solid phase speciation, dissolution, mineralization, precipitation and adsorption mechanisms of chemicals (contaminants and nutrients) in soils resulting from land application of domestic/industrial wastes. Prescription of waste reuse options & Best Management Plans for nutrients.

(3) Application of Soil Chemistry, Microbial Ecology, Plant Physiology, Biochemistry and Molecular Biology in Environmental Remediation Problems:
Evaluation of chemical, microbial and phytoremediation techniques to cleanup environmental contaminants. Biochemical and molecular biological techniques are employed to study the mechanism of heavy metal detoxification in plants, particularly Arsenic and Lead. Identification and characterization of genes involved in the metal detoxification pathway.

(4) Risk Assessment:
Estimation of ecological and human health risk for environmental decision-making, especially those involving protective and clean-up standards for contaminants already in the environment.
