biogeochemistry of nutrients and pollutants in soils
environmental chemistry and toxicology, specifically the assessment and remediation of contaminated soils
advanced techniques to measure and monitor nutrients and pollutants in the environment.
Instrumentation:
Liquid-phase speciation: HPLC-ICP-MS (Agilent 7500) combined with separation by tangentialflow ultrafiltration, centrifugal ultrafiltration, field flow fractionation, and Donnan dialysis
Soild phase speciation: Isootpe exchange, DRIFTS and synchrotron X-ray spectrosscopy (Melbourne, Chicago, and Tsukuba)
