Personal profile

Biography

  • BSc Geography, University of Manchester, 1997
  • MSc Environmental Archaeology and Palaeoeconomy, University of Sheffield, 2001
  • PhD in Physical Geography, University of Manchester, 2006
  • Post-Doc, 2007: Iron Age landscape on Myerscough Abbey grounds, Isle of Man, with Centre for Manx Studies
  • Post-Doc, 2007-2009: Deforestation of Upland Britain, supported by AHRC
  • Teaching Fellow in Geography 2009-present

I read for my undergraduate degree at Manchester and then returned to do a PhD in 2002 and have been at Manchester ever since. I am currently a Teaching Fellow in Geography. My work focuses on the environmental impact of prehistoric people through the use of palaeoecology.

Research interests

Environmental impact of Late Mesolithic (hunter-gatherer) cultures

The degree to which Late Mesolithic groups manipulated their environment is the subject of much debate. It has been argued that these groups manipulated woodland through the use of fire in order to improve grazing and browse resources for wild animals. This would increase and concentrate the numbers of game animals and improve the chances of hunting success. My research uses palynology to try to elucidate the processes occurring within the woodland landscape at this time. In addition to the more traditional pollen and charcoal analyses, I also use the fungal spore record as some fungal types can be indicative of particular host plants, burnt substrates and animal dung and thus can provide important additional information and insights. 

The Deforestation of Upland Britain

Most of the uplands of the British Isles are now treeless landscapes. Tree remains preserved at the base of and within the peat deposits that cover much of these uplands indicate that this was not always the case. What processes brought about the deforestation? Climate change, edaphic change, disease, human impact or a combination of these? I have directed an archaeological excavation of a small area of palaeoforest preserved in the North York Moors in order to use the tree macrofossil remains to look for evidence of disease, ring-barking/cutting, fire scars and the dendroclimatological record preserved in the growth rings of the trees. From a peat monolith recovered from the side wall of the excavation trench I also analysed pollen, charcoal and fungal spores to try to match up the palaeoecological proxies. 

The transition from Mesolithic hunter-gathering to Neolithic farming in North-West Europe

The adoption of agriculture is one of the most important transitions in human history. The nature and timing of the transition is the subject of much debate were people or ideas the agents of change? Was agriculture brought by immigrant farming groups or was it an adaptation by the indigenous Mesolithic population? Records of early cereal-type pollen grains from Mesolithic-aged contexts hint at the possibility that cereals were first used by Mesolithic groups or by pioneer Neolithic groups that left no other trace in the archaeological record. Through the use of pollen, charcoal and fungal spore data, my research aims to establish if these early cereal-type pollen grains refer to domestic (rather than wild) grasses, and if so, do they reflect the cultivation and use of cereal crops.
