Ullrika Sahlin

I am a lecturer in ecologic-economic modelling at Lund University. 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 bee health• Litter • Species conservation


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


We have now published android versions of the games about uncertainty on google app store. They are found by searching for UncertainGames. There are five English (Quiztimate, BeanGuesser, ProbabilityGuess, Probability Bee and FrequencyGuesser) and one Swedish game (Gisso).

The games are possible to download for windows and mac.

Upcoming workshops:

Quantifying uncertainty by probability. Lund October 10th. Stavanger November 7th


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. 

This is where you can download the risk analysis of signal crayfish report

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.
