Helen's research in surface water chemistry covers a broad remit: fundamental and applied research on the fate, behaviour and transport of macronutrients (phosphorus, P, nitrogen, N, and carbon, C), major ions, metals, trace elements, sediments and emerging contaminants (nanoparticles) to promote sustainable management of surface freshwater resources. She draws together key understanding of biogeochemical cycling and the impacts of pollutants and mitigation strategies on ecological integrity of river systems, in relation to climate variability, waste and effluent management, and changing rural and urban land use.
A major research focus is P and N in rivers, from UK to global perspectives, driven by concerns about eutrophication: a pervasive threat to water quality and water security. Given that society is reliant on P to grow our food, and that phosphate rock is a non-renewable resource, Helen's research also explores how improved P stewardship can ensure future food security and meet water-quality goals.
Over the last 20 years, Helen has published 120 papers (40 as first author) in international peer-reviewed journals, receiving over 4600 citations.
Helen's h-index is currently 42 (Web of Science); 44 (Scopus); and 54 (Google Scholar)
**Update** We have just published a new national-scale evaluation of eutrophication in Great Britain:
