Research Interests

In my PhD research I investigate how agents (individuals and groups) perceive and interact with their environments. Using the theory of affordances from ecological psychology, I am developing a method to overcome the foundational challenges that underly the semantic integration of human observations with technical sensor observation. In the course of my PhD studies I have also launched my research into resilience as well as agent-based modeling. My research is strongly interdisciplinary and encompasses fields such as Biology, Cognitive Science and Geographic Cognition, Communication Science, Computer Science, Cybernetics, Ecology, Environmental Science, Geoscience and Geographic Information Science, Logics, Philosophy and Psychology.  I frequently apply cutting edge technologies from semantic web research and ontology engineering to find novel solutions for Geographic Information Science.   download PhD Proposal PDF
