Rie Henriksen

Associate Professor

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.

Genetic architecture of brain structure - Henriksen Group

We use populations of both wild and domestic chickens to identifying the genetic architecture underlying variation in avian brain size and composition, as well as elucidating the effects and pathways of maternal stress.

AVIAN - Behavioural Genomics and Physiology group

The AVIAN - Behavioural Genomics and Physiology group at Linköping University studies the genetic basis of behaviour and physiology.

LiU researchers receive nearly SEK 19 million from Formas

Six researchers at Linköping University have been awarded research grants from the Formas research council. The supported projects cover a wide range: the challenges facing municipalities, nudging, and the genetic properties of boar sperm.

Epigenetics linked to differences between modern and wild chickens

Some of the genetic differences that have arisen between domesticated chickens and their wild ancestors, the red junglefowl, are linked to epigenetic changes. Scientists at LiU have discovered a small number of “hotspots” in the DNA that control

49 million Swedish crowns for research into sustainable development

Ten researchers at LiU have been awarded grants by the Formas research council. The projects include research into urban cultivation, the possibility of capturing carbon dioxide after emission, and the welfare of laying hens.
