Topic: Hybrid Petri Nets: An approach to modelling biological systems.

Speaker: Rob McLeay, ACCS Summer RA

Abstract:

Complex behaviour can arise from surprisingly simple biological networks. To study this behaviour, hybrid Petri Nets have been used as the modelling system, and several different biological networks modelled, including vulval development in C. elegans and the Growth Hormone cascade in mammals. With the hybrid extensions to Petri net theory, we have been able to produce useful qualitative or quantitative models of systems depending on the degree to which each system has been characterized. Hybrid Petri nets have proven to be an effective and intuitive modelling tool for biological systems, allowing many biological concepts to be easily and effectively expressed in the resulting model.
