My research focus on the quantification of uncertainty and how uncertainty is used in decision making and in particular the management of environmental systems under varying strenghts in knowledge.

Uncertainty and Evidence Lab (UnEviL)

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 strengths 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
Uncertainty in scientific assessments
Decision making under uncertainty
Bayesian analysis and its generalisation

Selected applications

• Ecosystem services in agricultural landscapes • Invasive species • Chemical safety • Honey bees • Litter

Stay tuned - in September I will announce a PhD position on ecological-economic modelling

I am interested in hosting postdocs or guest researchers on the topic uncertainty or ecological-economic modelling

Work interacting with stakeholders

A report on data collection and analysis of winter loss in Sweden is finished as part of the project Samverkan för god bihälsa - link here soon.

The project Gaming for better decisions under uncertainty is finished.

Education and awards

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.

2010 I defended my PhD thesis From data to decision - learning by probabilistic risk analysis of biological invasions. Prof Hugh Possingham was my opponent.

Award in the images of risk competition at ESREL 2016 of my image "The probablity of a unique event".

I received the Richard J. Burk Outstanding Service Award from the Society for Risk Analysis 2016.

Appointed Docent in Environmental Science at Lund university June 2017. The Swedish title Docent corresponds to Assciate Professor in the US or Reader in the UK. Here is a link to my docenture lecture.
