Earth habitability, from the origin of the continents to the oxygenation of the atmosphere

Welcome!

We study how the Earth became a habitable planet, from the origin and evolution of the earliest continents to the development of an oxygen-rich atmosphere. Our primary tools are radiogenic isotopes in rocks and minerals, which we use as chronometers and tracers in conjunction with stable isotope and geochemical compositions. We are also actively working on geochemical analytical technique development in order to expand the range of questions we can ask. Please refer to our Research page to learn more.
