Background

I obtained my BSc in Environmental Chemistry from the University of Edinburgh in 1995. I then began my PhD studies with Prof. James Maxwell (FRS) at the University of Bristol where I carried out research into the origin and significance of a group of biomarker compounds known as steryl chlorin esters (SCEs) which are produced by zooplankton when grazing on phytoplankton.

After completion of my PhD in 1999 I moved to Newcastle University and worked as a post-doctoral research associate with Dr Paul Farrimond on three projects in the area of hopanoid geochemistry developing new analytical techniques and providing new insights into the origins, diversity and complexity of natural distributions of these important biomarkers in modern environments and Recent sediments.

I am now a Reader in Organic Geochemistry and hold a European Research Council (ERC) starting independent researcher award.

Research Interests

  • The importance of methane as a climate driver in modern and ancient systems
  • The fate of terrestrial organic carbon at the land-ocean interface
  • Understanding and developing the potential of bacteriohopanepolyols as indicators of bacterial community structure, environmental conditions and biogeochemical processes in modern and ancient environments.
  • Using novel lipid biomarkers (BHPs, intact phospholipids, glycerol dibiphytanyl glycerol tetraethers etc.) to investigate microbial processes in soils, sediments, extreme environments etc
  • Analytical method development (including  HPLC and UHPLC, MS-MS, Ion-trap) and application of Liquid Chromatography-Mass spectrometry based analytical techniques in various fields including organic geochemistry and environmental studies.
