My PhD-project is on dogs' behaviour and the genetics behind it. Central is breed differences and within-breed differences. By studying this I can for example study how selection affects behaviour, for example dogs' social behaviour towards humans. I also study genetic markers interesting for, among other things, human-directed social behaviour to understand the genetics behind behaviour. Additionally, I'm working on epigenetic markers and differences in methylation between breeds and between the dog and the wolf.
