Your Tasks
We are seeking a highly motivated postdoctoral fellow with a strong biological background to join our interdisciplinary team at the interface of cell biology, biophysics, and tissue mechanics.
Project Overview
Epithelial tissues cover most internal and external surfaces of the body and must continuously adapt to environmental challenges while preserving barrier function. A key regulatory mechanism is cell extrusion, a process by which epithelial cells are eliminated from the monolayer, either as apoptotic cells or as living cells during EMT, morphogenesis, or early tumor invasion.
Our recent work highlights that mechanical forces, cell packing, and tissue stresses are major drivers of extrusion. However, how cells sense mechanical stress and how force determines cell fate remain largely unknown.
This project aims to understand how feedback between mechanics, adhesion, and signaling controls tissue homeostasis. We will particularly focused on the impact of physical cues on caspase activation, the role of neighboring cells, cell-cell adhesion and cytoskeleton perturbations during cell extrusion.
Research Objectives
The postdoc will investigate:
* How mechanical forces influence the fate of extruded cells (live vs apoptotic)
* How epithelial cells sense and respond to mechanical stress
* How extrusion contributes to tissue remodeling, morphogenesis, and tumor progression
Experimental Approach
We use in vitro epithelial models and ex vivo intestinal organoids, combining:
* Cell and molecular biology
* Live-cell and tissue imaging
* Cytoskeleton and adhesion analysis
* Microfabrication and mechanical perturbations
* Quantitative image analysis
This multidisciplinary project integrates physics-based approaches with experimental cell biology.
