David is joined by George Simmons, an impact activation postdoctoral fellow at IDEMS. In collaboration with CASAS Global, George has spent a year working on their Physiologically Based Demographic Modelling (PBDM) system, a style of modelling used to account for the ecosystem level dynamics that happen in a farm field. They elaborate on the project's integration with more modern mathematical techniques, the influence of the TOPOS Institute’s collaborative approach, and the broader implications of the work.
