Research
I am a geologist with broad research interests in understanding the evolution of Earth and the solar system. My main research tool is isotope geochemistry using novel isotopic proxies for addressing major scientific questions such as the geochemical evolution Earth and Pleistocene climate changes.
Much of my work focus on using uranium isotopes as a tracer of geochemical surface processes characterizing the global geochemical redistribution of uranium on Earth to quantify long-term global biogeochemical cycling and understand links with terrestrial weathering processes and oxygenation of the surface Earth. I am also using the decay products of the uranium isotopes to study a range of processes important for paleoclimate reconstruction, including uranium-series dating of fossil corals for sealevel reconstruction, continental weathering rates and its impact on ocean biogeochemistry.
