Molecular-level understanding the biogeochemistry of heavy metals and related nutrient elements (C, S and P) in soil-plant systems play a vital role in clarifying their mobility, bioavailability and cycling in agricultural ecosystem.My research seeks to provide a fundamental understanding of the controls on heavy metal mobility and bioavailability as well as nutrient stability and reactivity in soils using synchrotron-based techniques combined with additional NMR and NanoSIMS techniques.
