Having previously worked at the University of Birmingham, Fred completed his PhD in food web ecology and ecotoxicology from Cardiff University.
His research considered the transfers and effects of persistent pollutants in freshwater ecosystems. During his time at Birmingham and Cardiff he developed a range of interests relating to the ecology of river systems, with specific focuses on community- and food web-level processes. Over this time, he collated evidence on a range of pollutants and showed for the first time how microplastics enter the base of river food webs.
Ecosystem-scale processes form the basis of his work, be it investigating persistent pollutants in lowland river systems or the processes responsible for structuring communities in terrestrial ecosystems.
Fred is an early career committee member of the European Federation of Freshwater Sciences and a member of the Grants Committee of the British Ecological Society. He receives funding from the Royal Society.
