I am an Anthropogenic Contaminants Scientist with an expertise in microplastic pollution. I am especially interested in the interactions and effects of microplastics on organisms within aquatic environments. In order to understand how and why organisms will come into contact with microplastics, I am also keen to understand how the connections between land, lakes, rivers and the sea lead to the input, transport and accumulation of microplastics within the environment, and how ecological interactions may alter the fate and behaviour of microplastics. I have published studies identifying microplastics in UK rivers and freshwater fish,  in addition to experimental studies on the ecotoxicological effects of microplastics and organic chemicals on aquatic and terrestrial invertebrates. Additionally I have carried out research quantifying microplastics in treated and untreated wastewater and potable water products (manuscripts submitted). 

Alongside my research I lead the UK Microplastics Network (, working closely to integrate academic research with industry, policy and business to more efficiently address the variety of issues surrounding microplastics within the environment. I sit on the advisory panels of the Chartered Institution of Water and Environmental Management (CIWEM) and the Foundation for Water Research (FWR). I also regularly advise the Environment Agency and Defra on issues relating to microplastics research and management.
