Research overview

  • To understand the impacts of agriculture on hydrology and water quality and the effectiveness of land management strategies.
  • To quantify the fate and effects of emerging contaminants in the water environment.

My research focuses on the impacts of land-use on hydrology and water quality. Particular attention has been given to the effects of agriculture and I have researched the fate and effects of a range of pollutants, including nutrients, pesticides, veterinary medicines and sediment. Impacts on flooding have also been studied. Other work has investigated the impacts of upland land management on the delivery of sediment to reservoirs. Also in the uplands, I have undertaken several projects looking at dissolved organic carbon in surface waters. All of these projects have focussed on the development of sustainable land management strategies to improve water quality. To this end, I have carried out research for a range of key organisations, including Defra, the Environment Agency, Natural England, the water industry and the European Commission. 

PhD Supervision

I would be interested in supervising PhDs on topics such as:

  • Hydrology and water quality

PhD students

  • Wayne Duffus: Occurence and fate of emerging contaminants in river sediments.
  • Oloyede Adekolurejo: Ecological effects of cyanobacteria toxins.
  • Sarah Letsinger: Occurence and effects of pharmaceuticals in the marine environment.
