📢 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.
