Research
I specialise in agent-based modelling of socio-environmental systems, and rigorous approaches to their design and interpretation. Agent-based modelling involves explicit representation of individuals and their interactions, observing the emergent effects these have on the dynamics of the system. I am particularly interested in options for managing environmental change in coupled human-natural systems through incentive schemes, but in the context of other drivers of human behaviour. I have worked on agent-based modelling of lifestyles, pro-environmental behaviours and transitions to more sustainable ways of living, and current work continues this and is also examining value chains and resilience in Scottish rural systems.
A key issue in developing models of this kind is transparency, and I am interested in the role of formal ontologies in describing and annotating simulation models and experiments.
Past research
I have been involved the international and inter- and transdisciplinary research project, listed below
- The GLAMURS(Green Lifestyles, Alternative Models and Up-scaling Regional Sustainability) project (2014-2016) was funded by the European Commission’s Seventh Framework Programme.
