OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
The dynamics of a wide range of biological systems such as deformable cell layers, epithelial cells, bacterial colonies, and subcellular filaments can be described by the physics of active nematics. I will describe the main concepts used to build active nematic models and then highlight some of our work on how activity can build up orientational order, and lead to a state with continuous creation and annihilation of defects (locations in which the direction of cells is not well-defined). Finally, I will discuss some of our latest results on the role of activity in transitions from a 2D biological layer to 3D structures.
