I am an ecosystem ecologist, paleoecologist and stable isotope biogeochemist (yes I am a generalist). My research often involves applications of stables isotope techniques to various past and present ecological systems. Stable isotopic tools have allowed me the freedom to get involved in the wide range of research subjects, systems and locations that fascinate me. In many cases a better understanding how modern environments function can allow a better appreciation of how the past operated. A better understanding of past biotic responses to global change provides ways of testing environmental models, allowing future environmental scenarios to be assessed.
As examples, my interests include (but have not been limited to): investigating past animal ecology and environments, tracking the past movements of animals, examining nutrient and trophic dynamics and reconstructing past environments in East Africa, Iceland, Beringia and Belize. Spatial and temporal variability in the isotopic composition of materials in the environment often peak my interest.
Listed to the right are general research areas that I have an ongoing interest in. Some are linked to projects websites that have related to these areas of interest.
