Understanding our environment in the past, present and future is the challenge of Earth Sciences today.
Why study paleoenvironments
Paleoenvironments record interactions between geodynamic, surface and biotic processes.
Paleoenvironments enable to understand the Earth system during major changes and crises.
Paleoenvironments provide analogues to foresee the destiny of our changing Earth.
Paleoenvironments have shaped human evolution and now we shape paleoenvironments.
Many of my research projects focus on understanding why the world turned from a warm greenhouse to an icehouse state governed by ice-caps. Constraining paleoenvironments in this period with enigmatic hyperthermal events and transient ice shees to is key to understand high pCO2 climate.
I also participate in several projects on paleoenvironment and hominid evolution mostly within the East African Rift.
How study paleoenvironments
I believe that transdisciplinarity is the key for outstanding discoveries. The field of Earth sciences being transdisciplinary by nature is one of the most exciting!
I gathered a team of international scientists from trandisciplinary backgrounds. Together we:
- Acquire and date paleoenvironmental records in the field.
- Develop cross-calibrated paleoenvironmental proxies.
- Integrate proxies into geodynamic, paleogeographic and climate models.
These results are integrated to make paleoenvironmental maps using a QGis Plugin called Terra Antiqua that we are developing. The produced maps are shared onto Map.Paleoenvironment, an interactive platform to share and discuss.
Today, this field is bringing science at the heart of the societal and economical debates defining our responsibility in preserving and sharing our planet’s fragile environments and resources.
My goals are therefore to better understand Earth processes by exploring the interfaces with other scientific fields and communicate the implications of these scientific discoveries to society through teaching and outreach projects.
Hopefully this will contribute helping us live in harmony with Nature!
