Research Summary

I am an isotope geochemist, interested in developing novel tracers of carbon cycling in the past and present ocean. My tools are the isotopes of various trace metals (including copper, zinc, cadmium, nickel). These elements are micronutrients, which are essential in small amounts for life. At higher concentrations they are toxins, and their isotopes provide tools to trace the fate of anthropogenic contaminants.

Finally, trace metals are redox-sensitive, offering potential to reconstruct the co-evolution of oxygen and life on Earth.
