I am a NERC/ OU funded PhD student (2012 to present). The title of my PhD research project is ‘A multi-proxy isotope approach to reconstructing seawater oxygenation’.


My research is focused on the reconstruction of past ocean redox conditions through the application of novel stable isotope proxies. The main aims of my PhD research are to:

  • develop the rhenium isotope system as a palaeo-redox proxy
  • constrain the behavior of rhenium isotopes in the present day marine environments using sediments from a range of redox conditions
  • apply the proxy to samples from the Toarcian Oceanic Anoxic Event in order to gain new insights into the redox changes occurring during this event.
