June 25, 2026 - Proud to celebrate the work of two talented interns !
As we wrap up the 2025/2026 internship season, I would like to thank my two interns, who have been part of our team over the past few months:
🎓 Audrey Teillet (MSc in Marine Sciences – BOEM, Aix-Marseille University) investigated the productivity and photosynthetic dynamics of microphytobenthic biofilms across European intertidal mudflats under climate change, as part of the PEPR FairCarbon - CABESTAN and EU Horizon REWRITE projects (link).
🎓 Antonin Halouze (M1 SPE GEEL, La Rochelle University) explored how sea-level rise and increasing turbidity jointly affect microphytobenthic productivity in intertidal mudflats within the EU Horizon REWRITE project.
Working on complementary topics, Audrey and Antonin made a real contribution to our research while bringing enthusiasm, curiosity, scientific rigor, and a great team spirit to both the lab and the field. It has been a real pleasure to supervise them throughout their internships !
I am delighted to recommend both of them for the next step of their careers. Thank you both for your hard work, your motivation, and your positive attitude. Wishing you every success in what comes next!
June 04, 2026 - Upcoming Conferences
June 04, 2026 - Upcoming Conferences
I am pleased to announce my participation in two upcoming international conferences this summer, focusing on coastal and estuarine ecosystem functioning and the impacts of environmental change :
🌿 16th European Diatom Meeting
📍 Murcia, Spain | 🗓 July 6–10, 2026
I will be presenting a talk entitled: “Small warming, big shift: temperature-induced transition from carbon sink to source in diatom-dominated intertidal sediments along European shorelines”
More information about the conference: EDM 2026 official website
🌿 ECSA 61 – Estuarine & Coastal Sciences Association Conference
📍 Brussels (Square), Belgium | 🗓 August 24–27, 2026
I will be presenting a talk entitled: “Climate-driven stress and resilience of microphytobenthic biofilms: Implications for intertidal primary production and ecosystem services”
More information about the conference: ECSA 61 conference information
I look forward to engaging with colleagues, exchanging ideas, and discussing potential collaborations during these events. If you are attending either conference, feel free to reach out.

June 04, 2026 - New Published Research Article (Frontiers in Photobiology)
I am pleased to announce the publication of our latest research article: "Interspecific diversity in PSII photoinhibition and photoprotection of benthic diatoms during consecutive light and heat stress", now available in Frontiers in Photobiology
This paper presents part of the results obtained during the SEARCHLIGHT project (see details).
This study investigates how three estuarine pennate diatoms respond to repeated exposure to combined high light and heat stress, and how photoacclimation influences their tolerance. Using daily stress cycles, we compared PSII photoinactivation, photorepair, and photoprotection in Navicula phyllepta and Entomoneis paludosa, and Cylindrotheca closterium. Results show that benthic species efficiently recovered through strong photorepair, whereas the tychoplanktonic species showed higher photoinactivation and weaker recovery. Overall, diatom resilience mainly depended on species-specific traits and acclimation state.

January 29, 2026 - Precious memories that will stay with me for a long time !
Yesterday, I had the pleasure of taking part in the Children’s University at the University of Western Brittany (UBO) in Brest (France), as part of the Science Comes to Town project.
I gave a talk on the secret life of mudflats, aimed at children aged 8 to 14, told through nine key processes highlighting just how fascinating and essential these environments are to the functioning of coastal ecosystems.
A huge thank you to Enora Leproust for the organisation of the event, and special thanks to Agnès Payraudeau (PIC et pic), who illustrated my talk live. Seeing scientific concepts take shape through drawing added a truly engaging, educational, and poetic dimension to the presentation
Finally, a very special thank you to the more than 200 children who attended, for their curiosity, enthusiasm and contagious energy. They were extraordinary!
All the processes presented, directly drawn from the Mud-Cake Stories, can be found here

I created a short animated preview of my Mudcake Stories. This animation was produced ahead of an upcoming presentation of the Mudcake Stories for the children university involved in the Science Comes to Town project.
These stories explain the biological processes underlying the ecosystem services provided by intertidal mudflats, using simple metaphors and accessible imagery. The goal is to spark curiosity and make complex ecological processes easier to grasp.

January 08, 2026 - New Published Research Article (Photosynthesis Research)
January 08, 2026 - New Published Research Article (Photosynthesis Research)
I am pleased to announce the publication of our latest research article titled "Far-red light regulates phototactic behavior of benthic pennate epipelic diatoms under low irradiance" in the journal Photosynthesis Research.
This paper presents part of the results obtained during the SEARCHLIGHT project (see details).
This study investigates whether benthic pennate diatoms can detect and respond to long-wavelength light within intertidal sediments. Using multispectral LED illumination, we demonstrate that red and far-red light induce upward vertical migration even at very low irradiance. These findings suggest that diatoms possess a highly sensitive, spectrally oriented light-sensing mechanism that enables them to optimize their vertical positioning within sediments.
