*******************: EP24: Linking Life to the Landscape *******************

Research Interests

My background is in metamorphic and structural geology but these days my research is primarily focussed on understanding how geological factors (such tectonic displacement and lithology) interact with climate and life to control the dynamics of the Earth’s surface. I am particularly interested in the 4D evolution of river basins as they provide the link between the present (surface processes) and the past (the sedimentary record). Moreover, river networks and their associated basins provide the basic fabric for the organisation and evolution of life on our planet. The tools used to conduct my research include GIS/python for empirical analysis, and numerical surface process modelling (CHILD/CASCADE) to explore surface dynamics and field work. Over the years this work has taken me to the Antarctic, Aegean, New Zealand, SE Africa, the Himalayas, the Andes, and the British Isles.

Specific Research Topics:
* The longterm impact of vegetation on surface processes (with Prof. Tibor Dunai, University of Cologne, DE)

* How tectonic and climatic forcing affects biogeographical processes (with Prof. Dave Craw, University of Otago, NZ)

* The relationship between tectonic forcing of catchments and sedimentation (with Dr Hugh Sinclair, University of Edinburgh)

* The morphological evolution of river networks
