I am a palaeoecologist and biogeographer, with an academic background spanning physical geography, palaeontology and archaeology. My model for the understanding of the climates and environments of the last half million years in north-west Europe, using the evidence from mammalian biostratigraphy to identify discrete climatic episodes, now forms the established basis for our understanding of glacial-interglacial mammalian faunal turnover in the UK and beyond, and is widely employed by stratigraphers, palaeontologists, geochronologists and archaeologists. 

My research also sets the agenda for interpreting mammalian responses to abrupt climate change at the end of the Pleistocene, as well as addressing questions of long-term faunal history through glacial-interglacial cycles and reconstructing palaeodiet through multiproxy means. Increasingly, my research links to modern conservation initiatives, such as "re"wilding" and natural resource management, for example through investigation of source populations for reintroduction, nature recovery and the effects of large herbivores on the landscape.

Finally, my work extends into the GeoHumanities, through my long-standing collaborations with fine arts practitioners, animators and graphic artists and performance makers in order to examine societal responses to climate change and the evolution of scientific thought.
