Personal profile

Research interests

I am a physical geographer working internationally across a variety of locations and processes, and at a range of spatial and temporal scales. Since my PhD I have principally worked on carbon biogeochemistry in peatlands, specifically the role of fire on carbon dynamics. However, in recent years, my research interests have broadened to encompass a series of funded projects working at the interface between physical geography, social sciences, and planning. This latest interdisciplinary research examines the interactions between people and their local environment.

Research interests

  • Fire - prescribed fire & wildfires in UK peatlands; charcoal production and degradation; perceptions of fire
  • Organic soils - peatlands, wetlands, mangroves
  • Organic matter cycling through soils - oxidative ratio and carbon oxidation state
  • Urban green infrastructure

Opportunities

Postgraduate Opportunities

I welcome enquiries from well-qualified students wishing to carry out research in areas linked to my research interests.

I currently have a number of specific PhD research topics that I am keen to develop with motivated students:

  • Peat fires and their impacts on heavy metal mobilisation: many of the recent wildfires in the UK and across the Northern Hemisphere have occurred on peatland soils that are often contaminated by industrially derived pollutants e.g. lead, arsenic. How does the combustion of peat during smouldering peat fires affect the mobility of these pollutants in the terrestrial and aquatic environments? 
  • Charcoal in the Holocene record: the presence charcoal in the quaternary record is often used as a measure of wildfire in past landscapes (e.g. charcoal counts to infer wildfire activity). However, are these signatures truly a function of charcoal forming processes or are they modified by post-formation processes (e.g. transportation, burial)? 
  • Perceptions of UK wildfires: The UK has an underreported wildfire problem (see www.kfwf.org.uk for more details), though there has been increasing recognition over recent years. There is a strong and growing body of work on the physical processes and environmental impacts of wildfires in the UK, but relatively little work has been carried out using social science approaches. What are the perceptions of wildfires in the UK and how are they shaped by media narratives? 

Please feel free to contact me to discuss any ideas you might have in these areas
