Dynamics of bacterial colonies

 

 

 

An example experiment in which two seeds of bacterial colonies grow side by side for 10 days. The two colonies sense each other and growth in the direction of the neighbouring colony stops. The dynamics of the colony is modelled using a system of free-boundary reaction-diffusion equations. The system is solved numerically using level-set methods.

Dynamics of locust swarms

 

This is a new project that involves the dynamics of locust swarms. We analyse the multiscale nature of a swarm of locusts in a circular arena and suggest mathematical models for their dynamics.
