My research is focused on understanding the environmental context of human evolution in eastern Africa. I use stable isotopes to study modern and fossil terrestrial ecosystems.
Current projects include:
1) Reconstructing Plio-Pleistocene hominin paleoenvironments on the Homa Peninsula, southwestern Kenya.
2) Investigating how isotopic variability in plants, soils, and mammalian tooth enamel reflects climate and ecology acrossmodern environments in eastern Africa.
3) Stable isotope ecology of wild primates, and isotopic variation within tropical foodwebs.
4) Applying novel intra-tooth isotope microsampling strategies guided by the geometry of enamel mineralization for reconstructing environmental and dietary seasonality.
