Helen's research encompasses river-system biogeochemistry with particular emphasis on nutrient (phosphorus P, and nitrogen, N) cycling and water quality, from watershed to global perspectives. A major area is the role of nutrients in river eutrophication worldwide, and how improved nutrient stewardship can help ensure the future resilience of our river water quality and water resource 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.
