Joining the Department and the Water Institute in January 2020, 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.
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.
