Ullrika Sahlin

I am an Associate Professor of Environmental Science at Lund University. I do research on the quantification and communication of uncertainty in scientific assessments and how uncertainty can be considered in decision making, in particular in the context of management of environmental systems under varying strengths in knowledge.

I am looking for a postdoc to work on the characterisation of uncertainty in future risk assessments with applications to human health risk assessment. Please apply if you are interested in studying the quantification of uncertainty using subjective probability and the uptake of Bayesian reasoning in scientific assessment and integrated modelling in practice. https://lu.varbi.com/se/what:job/jobID:541436/

Uncertainty and Evidence Lab (UnEviL)

My research group focuses on the management of uncertainty and evidence in scientific assessment (risk assessment combined with evidence synthesis) and decision analysis. We discuss the principles and methods on conceptual and actual problems and we are not limited to a specific application. 

Key interests

• Uncertainty in scientific assessment
• Decision making under uncertainty
• Subjective probability and beyond
• New perspectives on Bayesian inference and modeling
• Biodiversity and ecologic-economic modeling
• Models for assessing chemical safety

Selected applications 

• Ecosystem services in agricultural landscapes
• Species conservation
• Invasive species 
• Food safety
• Chemical safety 
• Honey bee health

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 of 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 of 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.
