Helen’s main research interests are in river-system biogeochemistry, with particular emphasis on nutrient (phosphorus, P, and nitrogen, N) cycling, eutrophication, and water quality, from watershed to global perspectives.

Research Interests:

Helen's research explores the drivers of eutrophication and water-quality impairment; and how improved nutrient stewardship and safeguarding the functional integrity of our rivers and their watersheds can help build resilience in water-quality and water-resource security, within the context of climate variability and land-use change.  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 help ensure future food security and meet water-quality goals.

Helen’s research informs water-quality policy and decision-making, and addresses major societal challenges related to sustainable use of water and nutrient resources; managing environmental change and resilience; and improving society’s environmental legacy.

Helen is an Adjunct (Visiting) Professor in Fluvial Sciences at the University of Arkansas, USA; a Visiting Professor in Environmental Chemistry at Plymouth University, UK; and a Visiting Professor in Water Quality Science at the University of Tokyo, Japan. Helen is also a UK Centre for Ecology & Hydrology Fellow.
