Environmental Biology and Pollution Control in Agricultural Environment
Our research focuses on the chemical speciation, transformation and bioavailability of heavy metals/metalloids and persistent organic pollutants in agricultural systems. We use advanced analytical methodologies and molecular biology tools to investigate the mechanisms controlling the transformation of pollutants in soil and the rhizosphere, and their uptake by plants. We aim to develop practical methods to minimize the environmental risk of pollutants and to remediate contaminated soils. We are also interested in how plants cope with aluminum toxicity, which is a limiting factor for crop production in acidic soils.
