I am interested in the use and development of carbonate-bound geochemical proxies for palaeoclimate and palaeoceanograhic reconstruction, principally in the Paleogene and the Plio-Pleistocene. My work has so far focused on understanding the non-thermal controls on Mg incorporation into biogenic calcite, both to improve the accuracy of proxy data as well as to form the basis of new seawater chemistry reconstructions. A large part of this effort has focused on the live culturing of foraminifera in order to calibrate seawater-shell chemistry relationships. I am also interested in the use of emerging proxies, such as foraminifera Ba/Ca for salinity reconstruction, in order to constrain other aspects of the climate system.
Currently, I am working with Prof. Hagit Affek to produce new clumped isotope-derived ocean temperature reconstructions, focusing on the Paleogene.
I have extensive experience in the use of laser-ablation ICPMS for trace element analysis in carbonates, and experience with dual-inlet gas mass spectrometry for traditional and clumped isotope analysis. My publications include methodological development of laser-ablation as well as climatic and oceanographic reconstruction.
