My research mainly concerns the genetics of behavior in dogs, dairy cattle genetics and some studies related to developing countries.
Teaching
I am mainly teaching in the course Animal Genetics - Health, behaviour and welfare and in our introductory breeding courses.
Research
I have been involved in several projects that have been aimed at quantifying the amount of genetic variation (and covariation) in various types of traits in various species. The traits studied have been fertility, health, behavior, maternal ability, performance or production, and longevity; and mainly in the species dairy cattle, horses, and dogs. I have several collaborative projects with, e.g., VikingGenetics and Växa (regarding dairy cattle) and the Swedish Kennel Club.
