My research is aimed at understanding the origin of individual differences in behaviour and brain composition in order to answer questions about individual variation in stress resilience.
Presentation
I am a researcher within avian developmental and evolutionary biology with a strong background in avian mechanistic studies.
My research is mainly focused on explaining how differences in behaviour and brain composition between individuals of the same species can occur, and what underlying mechanisms enables this. I am especially interested in long-term effects of prenatal stress and the identification of stress sensitive genotypes.
My research can be used to answer fundamental questions about stress resilience and its link to behavioural complexity and brain composition and has direct implications for poultry welfare.
