Four days later, I think I can finally process this:

Iโ€™ve been awarded a Marie Skล‚odowska-Curie Postdoctoral Fellowship (#MSCA -PF 2025).

17,066 applications this year. ~9.6% funded.

Still feels slightly unreal.

Carbon Footprint Mitigation Policy Of The Climate Team, CEREGE The Climate team is conducting an experimentation to reduce its carbon footprint without hampering the effectiveness of our research.

Starting from today, all planned flights will be declared in advance to ensure we do not exceed our CO2 trajectory. If we exceed it, we will try to reduce it through collective discussion. More information here:
www.cerege.fr/fr/carbonmit...

Today, the climate team officially launched its carbon footprint mitigation policy. After one year of monitoring the carbon footprint of our trips (a total of 83 tCO2 for 90 persons in 2025), we voted to reduce this amount of 10% every year until 2030. (1/2)

Wonder what carbon was doing in the oceans before humans were around to see? We'll use the chemistry of tiny shells on the seafloor to find out how carbon moved between the ocean and atmosphere over 1 million years ago.

Come work with us in 2026 for your M2 internship @climatecerege.bsky.social.
