My PhD thesis is finally available online! 🎓
Check it out if you want to learn more about the fascinating hunting tactics of the diving predators of the Southern Ocean 🐧🦭

Hunting in the deep : unravelling the mysteries of Southern Ocean predator-prey interactions using innovative biologging technologies

Fine-scale interactions between predators and their prey, i.e. how predators find, select, and capture their prey, and alternatively how prey detect predators, and react to imminent predation, are key...

Last week, I had the pleasure of returning to my old high school to talk about my journey and research. 🐧For nearly two hours, we explored marine biology, ocean science, and career paths in research. 👩‍🔬Huge thanks to the students & teachers at Lycée Anna de Noailles for the great discussions! 🙌

🌿✨ World Wildlife Day ✨🌿

Today, we celebrate the beauty of wildlife. As a biologist and photographer, I capture these moments to raise awareness of their fragility and the need for protection. Every species matters!

📢 Today marks the 10th anniversary of the International Day of Women and Girls in Science 👧!

💡Encouraging women in science means enriching research, breaking stereotypes, and ensuring a fairer, more inclusive science ⚖️

This week, I had the pleasure of talking with the students from Ecole du Nord for their "Maritime Challenges" project, raising awareness about ocean richness and threats. We discussed about the top predators of Kerguelen Islands and their incredible survival strategies in the Southern Ocean 🌊🐧

In December, I had the pleasure to share my journey as a woman in science with bright, curious high school students as part of the "Têtes Chercheuses" event 👐. We had inspiring discussions about breaking stereotypes, overcoming challenges, and shaping the future through science! 🔬💡

The front cover, by Benjamin Dupuis, French Polar Institute, shows an Adélie penguin leaping from the water to return to its colony. @bendps.bsky.social & co report how depth tracking can estimate penguin energy use

Journal cover for issue 23, volume 227 of Journal of Experimental Biology. The cover includes an image of an Adélie penguin leaping from the water onto ice to return to its colony. The image is by Benjamin Dupuis @bendps.bsky.social – French Polar Institute

My first PhD chapter just got published in @jexpbiol.bsky.social ! We proposed a new framework to estimate foraging energetics ⚡ of Adélie 🐧 using TDRs. Our framework provided results similar to accelerometers and could likely be applicable on other diving predators 🐋🦈

To celebrate the end of my thesis on Southern Ocean predators 🦭, I’m selling limited-edition fine art prints from my expeditions 🌊🖼️. Printed on Hahnemühle Rag high quality paper, signed & numbered (only 20 per photo). DM me for details & bring the wild home! 🐧📷

Last week, I was delighted to defend my doctoral thesis on Southern ocean predator-prey interactions at the @CEBC_ChizeLab ! 🦭🐧
A big thanks to the whole lab for this amazing experience, and especially to my two wonderful supervisors!

New paper out!
We deployed sound and movement tags on Antarctic fur seals 🦭in Kerguelen Islands and recorded for the first time underwater vocalizations during foraging in this species 🎙️!

New paper out in @WileyEcolEvol !
I was very happy to be involved in this study about fine-scale predator-prey interactions in Weddell seals 🦭 using sonar tags for the first time on this species!

Another chapter of my PhD got published! In this study, we deployed new biologging devices on elephant seals 🦭 to describe fine-scale distribution and characteristics of their prey 🐟 in different oceanographic conditions.

Back from a great field season in the French Southern and Antarctic Lands! I spent one month on the small Amsterdam island to deploy GLS tags on subantarctic fur seals to learn more about their foraging ecology!
