Department of Theoretical Ecology
I am trying to understand and predict population patterns in time and space by combining statistical and theoretical analysis of ecological and environmental processes. My research interest covers fundamental questions such as: How does environmental variability translate into population fluctuations?, as well as applied issues of relevance for environmental monitoring and population management.
My overall research project is entitled Stochastic processes and population patterns: A unified approach to ecological inference and is financially supported by the Swedish Research Council. This project is part of the major research topic Stochastic Processes of Populations and their Environments and I collaborate with Dr. Martin Sköld at the Department of Economics, Statistics and Informatics, Örebro University.
I also belong to the Nordic Center of Excellence -
EcoClim.

My main responsibility is to teach ecology students quantitative methods, such as parameter estimation, model selection, and elementary decision theory. In 2007 I taught the following courses:
Experimental design (BIOS03) (main teacher)
Risk analysis in env. and public health (MVE201)
Biological Monitoring (BIOR39)
Fisheries Ecology (BIOR27)
