I am a geologist and geochemist interested in reconstructing the Earth’s climate and surface processes over geological history.
My D.Phil. research focuses on developing new ways to use the chemical signals preserved in stalagmites to reconstruct past continental environments and climate. This involves analytical work measuring trace metal and stable isotope ratios in the laboratory, along with development of chemical models to better understand the environmental processes controlling these signals.
