I work on climate reconstructions from marine sediments and stalagmites with a variety of geochemical methods. Recently I have focused on novel techniques to reconstruct past temperatures, most importantly clumped isotope thermometry. The CLIP and C4T projects will apply this technique to marine microfossils (foraminifera).
