Leah has a Masters in Earth Sciences (University of Cambridge) and a PhD in environmental science (University of Reading), specialising in modelling phosphorus dynamics at catchment scale. Since 2010, Leah’s research has focused on catchment hydrology and biogeochemistry, in particular eutrophication of lowland water courses and nitrogen leaching in uplands. She uses a combination of monitoring, statistical modelling and process-based modelling to better understand the controls on freshwater quality, and to explore the relationships between land management, climate change, surface water quality and ecological impact. Prior to joining NIVA, Leah was at the James Hutton Institute in Scotland, where she still holds a Research Associate position. During that time, she worked in a highly inter-disciplinary team to support the development, implementation and assessment of policies aimed at protecting surface waters, e.g. the Water Framework Directive. Leah has lead or taken part in a number of Scottish, UK, North Sea Region (Interreg) and EU projects. Leah is co-author of a book on the landscape and geology of Scotland, has published 10 international articles/book chapters, and has written over 15 contract reports.
