Prof. T. Bas Rodenburg is Professor in Animal Welfare at the Faculty of Veterinary Medicine of Utrecht University in The Netherlands. The research of Bas Rodenburg aims at improving the methodology for assessment of animal welfare. Rodenburg and his team try to ask the animal itself how it experiences its own living conditions. They do this by looking at the choices that animals make, their behavior and body posture and by listening to the sounds that animals make. By developing methods to better assess animal welfare, the group provides tools to improve animal welfare in practice. Rodenburg and his team increasingly use modern techniques such as AI, sensors to track animals and sound analysis using bioacoustics. These techniques offer the group the opportunity to continuously monitor animals and thus make more informed statements regarding their welfare. Bas Rodenburg was project leader of the EU Demonstration project Best Practice Hens, focusing on enabling the transition to cage-free housing for laying hens. Currently, he is work package leader in the EU project aWISH, focusing on monitoring animal welfare at the slaughterhouse and using that information to improve welfare of pigs and broilers on farm, during transport and at slaughter. Rodenburg is a member of the Dutch Council on Animal Affairs (RDA) and has been one of the architects of the concept of Humane Livestock Farming in The Netherlands. He is also Joint Editor in Chief of the scientific journal ‘Animal Welfare’.
