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!

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! 🔬💡

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 🐋🦈

My first PhD chapter has just been published in @PNASNews! We show that elephant seals 🦭are able to detect their prey at a long distance enabling them to set up stealth approach tactics and to find enough prey in the vast Southern Ocean 🐟
