Leah is primarily interested in biogeochemical processes acting at various spatial and temporal scales, in particular simulating long-term changes in soil and surface water chemistry in response to changes in acid deposition, land use and climate. Forthcoming projects include quantifying the impacts of pollution (particularly nitrogen deposition) and climate change on alpine heathland biogeochemistry. She will also be involved in modelling the impacts of climate change on aquatic ecosystems as part of the EU project REFRESH.
