My research is interdisciplinary by nature and lies at the intersection between paleoenvironmental reconstruction, plant and animal eco-physiology, anthropology and archaeology. I primarily, but not exclusively, use stable isotope methods to reconstruct past environment, the mobility and migration of past human societies, paleodiet and past human economic systems. My research program begins in the contemporary world, by investigating the mechanisms that cause variability in the ratios of stable isotopes as they move along foodwebs: from soil and atmosphere, to plants and from there to animals and humans. In many cases, the present day variability in stable isotope values provides suitable models to reconstruct past conditions with a high degree of certainty. The principles established as part of my contemporary work can thus be applied to ecological settings in the present and to paleoecological and archaeological settings in the past.
