Research is directed toward developing basic soil chemical principles and applying these principles toward solving environmental and agricultural problems. Current program emphasis is on (i) speciation and solubility of phosphate in soils as affected by redox potential, (ii) characterizing solid-phase speciation of heavy metals in contaminated soils using molecular spectroscopy and (iii) characterizing molecular-scale interactions of contaminants with clay mineral surfaces and organic matter.
