@juliemeilland.bsky.social won this year’s Alan Higgins Award! We cite: « her pioneering work on planktonic foraminifera - including the first multi-generational lab cultures - has transformed how we study and apply these vital microfossils. »
Yay!
Yay!
I was awarded the Alan Higgins Award by @micropalaeosoc.bsky.social for my work on planktonic foraminifera reproduction and culture. I feel very honored and can only thank all the great colleagues who supported me along the way in Norway, Ireland, the UK, Germany and France!

Interested in improving our knowledge of climate by looking into the past? In the Pliocene the earth was hotter than today, but carbon dioxide was "about the same".
Come work with us in 2026 looking at where this crucial information comes from, and how to make it better during an M2 internship.

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.
