A marine biologist for more than two decades, his research focuses on the effects of plastic debris in the marine environment, the modification of coastal engineering to enhance biodiversity and the ecology and conservation of shallow water habitats.
In 2004, he published a seminal piece of research in Science in which he coined use of the term microplastics to describe the microscopic plastic fragments found in our oceans.
Since then, he has been involved in a number of key discoveries including demonstrating the potential for microplastics to transport chemicals to marine life, and the global distribution of microplastics from shorelines to the deep seas and arctic sea ice.
He has contributed to government legislation on single-use carrier bags and the use of microbeads in cosmetics, and given evidence to parliamentary inquiries in which one politician referred to him as the “Godfather of microplastic research”.
He has also delivered numerous international presentations, including speaking at John Kerry’s ‘Our Ocean’ conference in Washington, DC in 2014 and other events organised by the United Nations and the Organisation for Economic Co-operation and Development (OECD).
At the University, he for many years led the BSc (Hons) Marine Biology course, on which he continues to teach on several modules and to coordinate an annual fieldwork trip to Portugal.
He conducts research projects with undergraduates and postgraduates, with studies involving the degradation of plastic carrier bags, the breakdown of fabrics while washing clothes and the prevalence of microbeads in cosmetics all being published with university students.
