Research Summary
Research interests are primarily the chemistry aspects of environmental contaminants and interactions in the soil-plant-water ecosystems, in the context of specie transformation, environmental fate, risk assessment, and remediation. Recent activities have focused on in situ metal immobilization (Pb, As) for exposure and ecological risk reduction in contaminated soils, aqueous metal (Pb, As, Hg) and organics (atrazine, TNT) removal by chemically-modified activated carbon and nano-structured carbon tubes, plant species-specific rhizodegradation of munitions explosives (TNT, RDX), application of fluorescent emission spectroscopy for water quality assessment (DON, DOC, DBP), and development of micro-chip sensor array (pH, O2) for studying rhizosphere interactions.
