More than just a barrier: using physical models to couple membrane shape to cell function
The correct execution of many cellular processes, such as division and motility, requires the
cell to adopt a specific shape. Physically, these shapes are determined by the interplay of …

From collections of independent, mindless robots to flexible, mobile, and directional superstructures
A swarm of simple active particles confined in a flexible scaffold is a promising system to
make mobile and deformable superstructures. These soft structures can perform tasks that …

Green algae scatter off sharp viscosity gradients
We study the behaviour of the green alga Chlamydomonas reinhardtii (CR) in the presence
of neighbouring regions of different viscosity. We show that the velocity and angular diffusion …

Modelling cellular spreading and emergence of motility in the presence of curved membrane proteins and active cytoskeleton forces
Eukaryotic cells adhere to extracellular matrix during the normal development of the
organism, forming static adhesion as well as during cell motility. We study this process by …
