Biography

I am responsible for teaching all physical geography papers at St John's College. I am a Quaternary Scientist with research interests in palaeoenvironmental change in dryland regions, geoarchaeological applications and the development of luminescence dating as a geochronological technique. I collaborate with colleagues at national and international institutions and my current research projects include: 

  • Reconstructing late Quaternary palaeoenvironments in the Indian sub-continent
  • Reconciling dust flux and fluvial activity in the Namib Desert
  • Quantifying late Quaternary fluvial and aeolian activity in Central Australia
  • Optimising the luminescence signal from quartz for dating applications
