Head of Environmental Sustainability Research Centre
As the Head of the Environmental Sustainability Research Centre, I oversee reserach and academic enterprise. I am Programme Leader for the MSc in Environmental Assessment and Control, and for the PG Cert in Managing Urban Drainage. I teach on various aspects of environmental pollution, biogeochemical cycling of environmental contaminants, bioavailability and speciation of toxic and essential elements in the environment, toxic elements in the human food chain and their human exposure assessment.
My research interests lie in the area of biogeochemistry of elements in the water-soil-plant-human pathway to understand the links between the geochemical environment and the health of plants, animals and human beings. My current research work is in two main areas:
- mobility, bioavailability and speciation of toxic trace metals in different environmental media and their impacts on biota including human beings
- micro-anionic nutrients in the environment and their significance to human health.
