Current Research (School of GeoSciences, University of Edinburgh)

The main aims of my current research are to study the environmental controls over soil organic matter decomposition and the biogeochemical processes responsible for soil carbon stabilisation. I am currently working as a lecturer in ecological sciences. I'm a member of the Scottish Alliance for Geoscience, Environment and Society (SAGES) Theme 2, the Terrestrial Carbon Cycle and I recently worked as a SAGES biogeochemistry of soils research fellow.

PhD Research (School of GeoSciences, University of Edinburgh)

My recent PhD research involved the study of chemical records of environmental pollution in ombrotrophic peat bogs. The main aims of this research were to use ombrotrophic peat bogs to reconstruct records of past and present atmospheric metal deposition in Scotland. This work involved the determination of elemental concentrations (Al, As, Ca, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Na, Ni, P, Pb, S, Sb, Ti, V, Y, Zn and Zr) and Pb isotope ratios (206Pb/207Pb) in peat using ICP-OES, ICP-MS and CVAAS as appropriate.
