Presentation

My research focuses on methods for forest planning and systems for decision support in a multi-purpose forestry. I am currently the program manager for the Forest Sustainability Analysis (SHa) program, which runs projects in this field. SHa is also responsible for the management and further development of the Heureka system, which is a decision support system developed at SLU intended for multi-purpose forestry 

Undervisning

My teaching is currently of a smaller scale. At present I participaten in teaching in in course Forest Planning with PlanWise as Decision Support(SG0226). 

Handledning

I'm principal supervisor for one PhD student, Patrik Ulvdal. His topic concern the influence of data quality on planning and decision processes in forestry.  som arbetar med frågor som rör datakvalitetens inverkan på skogliga planerings- och beslutsprocesser. In addition, I am an co-supervisor for three more doctoral students.

Tidigare har jag varit huvudhandledare för:

- Lars Sängstuvall, dissertaion 2018: Improved harvesting technology for thinning of small diameter stands. Impact on forest management and national supply of forest biomass.

- Rami Saad, dissertaion2017: The effect of forest information quality on the planning and decision process in forestry,

- Sofia Backéus, dissertaion 2009: Forest management strategies for CO₂ mitigation.

- Karl Duvemo, dissertaion2009: The influence of data uncertainty on planning and decision processes in forest management.
