My research focuses upon landscape- and environmental change in time and space and how these changes are influenced of both social and natural factors. Human interference and in particular our use of natural resources is central. I’m interested in how traditional land use has shaped our cultural landscapes and how abandonment of this use interacts with concurrent environmental and climate effects.

I'm responsible for teaching within GIS, Remote sensing and cartography. We offer the following courses:

• GEO110: Cartography and thematic maps
• GEO115: Cartography and field mapping
• GEO215: Geographical Information Systems: Theory and Practice
• GEO313: Field and Laboratory Methods in Physical Geography
