Research interests:

My research interests lie in the field of environmental monitoring and modelling with a particular interest in the application of novel monitoring technologies. The focus of my PhD was in the newly emerging field of in situ high-frequency hydrochemical monitoring and I have continued to develop this in my post-doctoral research. I am interested in using the new datasets, attainable through this type of monitoring, to advance the understanding of catchment biogeochemical processing, and how in stream processes are linked to wider catchment processing in the soil and hyporheic zone. The combination of these datasets together with novel numerical analysis approaches and experimental data, are revealing new insights into the controls on instream biogeochemical processing and the role these processes play in nutrient cycling. I also interested in how these processes= will be affected by future environmental change and what implications this will have for the achievement of legislative standards.
