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).

I am leading two research projects on clumped isotope thermometry in foraminifera. The C4T project is a Starting Grant from the ERC (European Research Council), and the CLIP project is funded by the Bergen Research Foundation and the Department of Earth Science.
