My research is directed towards the practical implementation of normative theories for decision making under uncertainty. I take inspiration from the management of environmental systems given the current state of knowledge. 

Uncertainty and Evidence Lab

This research group focus on the management of uncertainty and evidence in risk analysis, evidence synthesis, decision analysis and, never the least, predictive sciences. This include discussing and applying principles and methods for learning, forecasting and decision analysis under different strenghts in knowledge. We seek to apply the principles and methods on conceptual and actual problems and we are not limited to a specific application. 

Key interests

  • Environmental decision making
  • Process-based modelling
  • Decision making under uncertainty
  • Bayesian analysis and its generalisation

Selected applications that I have worked with

• Ecosystem services in agricultural landscapes • Invasive species • Chemical safety • System safety and reliability • Forestry • Conservation 

Current work interacting with stakeholders

Independent expert in the MUST-B working group at EFSA • Risk analysis on the signal crayfish for the Swedish Water Agency • President of the Nordic Chapter of the Society for Risk Analysis

My education

I have a Master of Science in Mathematics with a major in Mathematical Statistics, Lund University 2003. My Master thesis "Analysis of forest field data with a spatial approach" was awarded Sparbanksstiftelsen Skåne Nova scholarship on 25 000 SEK 2004. I also have a Master of Science in Forestry with a major in Forest management, Swedish Agricultural and Forest University, 2000. My master thesis "Modelling spatial variability in low temperature at a landscape level" was awarded Arvid Lindman scholarship on 25 000 SEK in 2001.
