Lecturer in Environmental Ecology
I research the ecological (plant and soil) responses to atmospheric nitrogen pollution. I am responsible for the management of 2 field-based nitrogen (N) addition experiments (Lowland Heath and Upland heath) and involved in several more including Acid Grassland and Bog habitats. I also led a national DEFRA Funded survey which aimed to understand ecosystem responses to atmospheric pollution in key semi-natural habitats across a climatic gradient. I have played a key role in a number of governmental reports, which fed into policy development, and several published journal papers.
I recently completed a NERC Policy Fellowship with the Environment Agency, which aimed to understand how we can more effectively legislate for the effects of N pollution at our protected sites. Part of this was a critical review and gap analysis of the use of dynamic modelling to better understand the temporal component of N pollution; interpreting the relationship between N, different response metrics and conservation outcomes; interpretation of Science Reports as part of the Environmental Permitting process of UK coal-fired power stations.
