Short presentation
Irena Czycholl studied veterinary medicine at the School of Veterinary Sciences, Hannover, Germany, where she also obtained her PhD in a larger joint project about the market entry of a national welfare label into the pork supply chain. After a short time as practising veterinarian, she worked as postdoctoral researcher at Kiel University (Germany) focussing on welfare assessment in farm animal husbandry. She also analysed the influences of changes in husbandry on the behaviour in farm animals as well as the understanding of causal structure leading to behavioural disorders. After becoming a senior research scientist for applied animal behaviour and welfare in pig industry, she is now continuing her research on animal welfare and animal behaviour at the faculty of Health Sciences - University of Copenhagen.
