I am Professor of Exposome Science in the Centre of Pollution and Policy at Brunel University of London. My research covers a range of topics in environmental, analytical, exposome and water sciences. My work is focused on the development and application of high resolution MS and MS/MS techniques for the determination of environmental contaminants for assessing animal and human exposure to contaminants in the environment. My work involves the study of the fate and behaviour of priority pollutants and emerging chemicals in the aquatic and terrestrial environment and the development of sustainable water treatment processes for the removal of hazardous substances from wastewater. Key areas of my research are concerned with the determination of the formation and occurrence of disinfection-by-products and the identification of emerging contaminants in the environment, potable water and wastewater.
