- Functional connectivity in fragmented landscapes
- Range shifting in response to environmental change
- Modelling dispersal and its demographic consequences
- Development and application of individual-based simulation models
The main focus of my current research involves modelling the dispersal of organisms (mostly animals) and its consequences in terms of demographics and functional connectivity between populations in fragmented landscapes.
Principally, I use spatially explicit individual-based simulation models to address these issues. In particular, I have been involved in the development of the Stochastic Movement Simulator (SMS), a simple algorithm for representing movement on a cell-based cost surface subject to limited perceptual range, and RangeShifter, a modelling platform which combines a number of demographic and dispersal models (including SMS).
