Dr Romain Guilbaud

I am a geologist, and my research broadly addresses the chemical evolution of the Earth’s environment. I combine multidisciplinary approaches including geology, isotope geochemistry, experimental geochemistry, organic and inorganic chemistry in order to constrain the processes which have shaped the Earth’s surface towards a habitable planet.

My current research focusses on the Ediacaran-Cambrian transition, a period of time which has witnessed the emergence of animal life. The distribution and the preservation of early animal communities highly depends on the oxygenation of the oceans in which they thrived. Together with palaeontologists, I am evaluating the history of the ocean’s oxygenation against our archives of exquisitely preserved fossils, in order to draw an emerging picture of the interactions between biology and the environment at the rise of early animals.
