As a paleoclimatologist, interested in reconstructions of past climates, I conduct research at the interface of geology, chemistry and biology. The main aim of my research is to improve the methods we have for reconstructing climate in the geologic past in high detail. Examples of such high-resolution climate reconstructions include reconstructions of seasonality and decadal variability in climate over long timescales (in "deep time"). Fossil bioarchives such as bivalve shells record changes in the environment in which the animal grew at this fine detail, and therefore form ideal archives for these reconstructions.
In my research, I combine detailed analyses of microstructures and chemistry in these fossils as well as in modern organisms to learn more about how the chemistry of these bioarchives records environmental conditions, and how we can use these fossils for accurate reconstructions of high-resolution paleoclimate.
In addition, I also strife to improve analytical methods that enable us to measure chemical variability in bioarchives with high precision and accuracy. These methods include stable and clumped isotope analysis, laser ablation ICP-MS and micro X-Ray Fluorescence.
