Postdoctoral researcher in molecular plant biology on weekdays. Ecologist in the weekends. Science is not a profession, it is a way of life🌱

My second “pilgrimage” to the home of Darwin. This museum perfectly captures the excitement of the scientific discoveries in the 1850s. His garden is a big experimental playground. Highly recommended!!!

📢 Two postdoc positions available in @mc-caillaud.bsky.social's group (RDP lab, ENS de Lyon), part of an ERC Consolidator. Project: how plant cells orient their division, combining cell biology, molecular genetics, and mechanical modelling. 📅 Deadline: 1 Oct 26 | Start: Nov 26 onwards Details 🧵👇

Recruitment flyer for two postdoc-funded positions in Marie-Cécile Caillaud's group (RDP laboratory, ENS de Lyon, France). Across the top run six scientific images: a line drawing of an Arabidopsis seedling with roots; a 3D digital reconstruction of a shoot apical meristem with orange and purple sectors marking cell lineages; a confocal microscopy image of plant tissue with green cell outlines and red/orange fluorescent nuclei; two paired 3D cell models in orange/green and yellow/purple showing division plane geometry; and a fluorescence microscopy image of a dividing cell with yellow microtubule-like structures and cyan nuclei on a dark background. Below, the title reads "Two Postdoc-funded positions" with an ERC logo, followed by "Deadline: 1st of Oct 2026" and "Starting date: Nov 2026 and onwards" in a bordered box. The body text is organised into sections: PROJECT (describing research into how plant cells orient their division, combining cell biology, molecular genetics, and multiscale mechanical modelling, with a link to the team website), CANDIDATE (looking for motivated candidates with a strong publication record, prior expertise in plant cell biology or biophysics as a plus, working language English), ENVIRONMENT (describing the ERC Consolidator project, the RDP laboratory hosted at ENS de Lyon, an international and gender-balanced working environment, and the city of Lyon), and RECENT PUBLICATIONS (three pinned references: Goldy et al. 2026 in Science Advances, Gascon et al. 2025 in Current Biology, and Lebecq et al. 2023 in Science Advances). An envelope icon box at the bottom right gives instructions to send a single PDF (cover letter, short summary of previous research, CV with publications, and contact details for two to three referees) to marie-cecile.caillaud@ens-lyon.fr.

Our work on the mechanoresponsiveness of actin is out! While plant microtubules have been extensively studied for their role in mechanobiology, actin has very much been ignored. Here we show that actin responds to cellular deformations within minutes and observed it in Marchantia and Arabidopsis!

We're hiring a PhD candidate! 🔬 Are you fascinated by cytoplasmic genetics and eager to uncover the mechanisms underlying maternal inheritance of plastids and mitochondria? If so, join our group and contribute to our ERC-funded research "CytoInP"!🌟 Application link: www.wur.nl/en/vacancy/p...

PhD position: Manipulating plastid and mitochondrial inheritance in plants

Our group investigates the maternal inheritance of plastid and mitochondrial genomes in plants, with the goal of uncovering the mechanisms that govern this process.

Last week I stumbled on a study to ferns in storm drains in 2007. I contacted the author and now I am revisiting the hotspots. Today I found the same species on the same locations as 20 years ago. This is remarkable as spores are unlikely to escape the drains, making this mini-ecosystem very fragile

Seed banks coming alive! This soil was removed from a forest mid March. It is the perfect growth substrate as it came from a forest that had been around for at least two centuries. Currently, such old forest grounds are protected by law, but our local government wants to lift the protection…

My wife recently made a career change to become a primary school teacher. Today she discovered that 20% of her class (12 year olds) did not know whether a swan is a fish or a bird… Something is terribly wrong with our educational program… and it shows how disconnected we are with nature…

A great way to close the #PlantWallK26 days in Prague! The EPCC satellite meeting wrapped up yesterday with a full day of scientific presentations and stimulating discussions on plant cytoskeleton. Many thanks to all contributors and participants, it was a pleasure to see the community in action.

Group photograph of EPCC satellite meeting participants, taken on 27 May 2026 in the entrance hall of a classical university building in Prague. Approximately forty attendees are arranged across several steps of a grand stone staircase, facing the camera. A small sign reading "EPCC — May 27.5.2026, Prague" is held at the front of the group.

We revisited the evolution of plant actins (last paper was in 1999), with the aim to understand why plants have many actin isoforms and how these isoforms can be functionally different. Strikingly, unlike e.g. the auxin response factors, actins are completely segregated per taxonomic lineage. (1/n)

My lycophyte photo was featured in the @waarneming.nl newsletter! Really cool, considering that there were already 2.2 million observations in 2026 and only 3 newsletters 😍. I took it to highlight the microphylls
