Approach
Due to the nature of this project, a wide range of modelling techniques are required to help understand the validity and guide experimentation in the wet lab. The reason for this is that in addition to the creation of synthetic genetic circuits to regulate the internal state of a cell, we require the cell to physically interact with the environment in such a way that by bringing a large number of them together, all following to same rules, emergent behaviours are exhibited - the ultimate outcome of the project. To do this it is necessary to take into consideration the movement and physical force exerted within an environment.
TODO: Discuss the modelling approaches for GRNs and the stochastic simulations
Both types of model we require will make use of computing resources. We are looking to utilise MATLAB for tasks such as numerical integration and statistical analysis and Java for the development of a stochastic agent based framework that will allow us to simulate bacteria chemotaxis, physical interactions between bacteria/particles and chemical fields, including diffusion. The simulation environment will form the majority of the modelling work and once we can incorporate the GRN dynamics within each bacterium (agent) we hope to be able to perform virtual experiments that mimic those in the wet lab.
The major limitiation of this approach is the

| To understand the dynamics of genetic networks that we design, differental equations are used to model the changes in concentration of mRNA and proteins. | With the project requiring global behaviour to emerge via the physical en masse movement of bacteria, stochastic agent based simulations are used to investigate the viability and limits of different approaches. | With the aim of improving simulation accuracy this model integrates the intercellular GRN dynamics with the extra-cellular interactions of the stochastic agent based simulation. |
