The complexity is inherent to ecological and anthropogenic processes. My research interests lie in learning more about spatial and temporal relationships and interactions driving changes in our world. Spatial analysis, modelling and geographic information systems help to study complex problems, such as climate change, landscape ecology and forestry, by explicitly representing phenomena in their geographic context. The research developed at LEDGE makes use of the inherent multidisciplinary field of geographical information science (GIScience) applied to investigate the relationships between ecological processes, environmental changes and spatial patterns.
