Gulliver seminars take place on Mondays at 11:30 AM in the F304 room, and typically last one hour including questions. The seminars are in English, and the scientific topics are mainly those studied in the laboratory.

Active Matter : evading the decay to equilibrium
Biological systems avoid equilibrium by taking chemical energy from their
surroundings and using it to do work. Cells organise intra-cellular components into
the structures that allow them to grow, reproduce and move. Tissues, collections of
cells, differentiate locally as they develop to perform the complex functions of
different organs.
Active systems, also exist out of thermodynamic equilibrium. Dense active matter
shows complex collective behaviour and mesoscale turbulence, the emergence of
chaotic flow structures characterised by high vorticity and self-propelled topological
defects. I shall describe the physics of dense active matter and discuss possible
links to motility and morphogenesis in biological contexts.

The audience is often heterogeneous - because of the wide range of scientific topics covered in the lab - so planning a talk for a broader audience would be preferred. The seminar is in English, and speakers are thus invited to prepare their slides in English.
The seminar starts at 11:30 AM. The speaker is asked to arrive in the lab at least 15 minutes in advance to set up their computer. The talks last typically 45 minutes, and are followed by a discussion time.
