Assembly and polarization of the Golgi apparatus

The architecture of the Golgi apparatus is remarkably complex. In mammalian cells, it is composed of stacks of disk-shaped membrane compartments that are laterally connected to form a ribbon-like structure. These...

Nicolas Biais

Back to Basics to go Beyond.

Séminaire réservé aux membres du LJP.   In our wonderfully interdisciplinary lab, we might not always grasp the full breath of shared knowledge. What is trivial, or second nature, to some might be extraordinarily...

Polar Active Solids : from collective actuation and synchronization to weird mechanics

Active matter exhibits rich collective phenomena at large scales, such as new types of phase separation and/or collective directed motion. The past 25 years have seen a surge of experimental observations and...

Renaud Bastien

Perceptual Matter and the Virtual Reality Experimental Machine

Understanding how organisms integrate environmental and social information to coordinate their actions is a fundamental scientific question. Collective animal behavior, observed in phenomena such as the synchronized...

Julien Husson

Cell Mechanics and Mechanobiology: Micropipette-Based Developments and Applications to Immune Cells, Parasites, and Phototoxicity

Understanding the mechanical properties of cells requires quantitative, time-resolved techniques adapted to non-adherent biological objects. I will present developments around a profile microindentation technique...

Ashley Nord

Probing spatiotemporal electrochemical dynamics on single bacterial cells

Electrochemical gradients across biological membranes are fundamental to cellular bioenergetics. In bacteria, the proton motive force (PMF) drives critical functions such as ATP synthesis and motility. Although...

Pierre Recho

Protrusion-driven initiation of motility on a compliant substrate

The conditions under which biological cells switch from a static to a motile state are fundamental to the understanding of many healthy and pathological processes. In this talk, we consider a cell constrained to move...

Single-cell imaging approaches to study cell division homeostasis

Cell division homeostasis is essential for long-term cell survival and for the ability of cells to adapt to fluctuating environments. Our work aims to understand how cells integrate internal and environmental cues to...
