I studied Biology and Philosophy at the University of Muenster and finished my diploma thesis in 1999. Subject of the diploma thesis was the evaluation of housing conditions of laboratory mice from an animal's point of view using preference tests. In brief: If mice have the choice, they prefer enriched housing conditions and will even work (pressing a lever up to 16 times per entry) for the access to a more entertaining housing system.
In my PhD-project "Behavioral Phenotyping of Mice: Methods, Evaluation, and Appliance" I investigated BC1-RNA knockout mice by means of a battery of behavioral tests. Tests were carried out with different knockout lines in different laboratories. The combined results indicate that although BC1 RNA does not code any protein, it seems to be involved in the modulation of explorative behavior.
In 1999 I programmed a tracking software using digital image processing techniques in order to automate data acquisition (for details on animal tracking those days, see "Digital Image Processing in Behavioral Sciences"). From 2004 to 2013 I worked at the Department of Behavioural Biology in Muenster as a researcher continuing my work with transgenic mice. From 2006 to 2010 I also was the managing director of the Otto Creutzfeldt Center for Cognitive and Behavioral Neuroscience (OCC), an association for research and education spanning different faculties of the University of Muenster focusing on behavioral neuroscience. From May 2013 to March 2016 I was employed as an interim professor at the University of Osnabrueck acting as the head of the Department for Behavioral Biology. From September 2016 to March 2017 I worked as an interim professor at the University of Goettingen. Since April 2017 I am a professor for animal welfare and refinement at the Freie Universität Berlin and the Head of Unit "Laboratory Animal Science" at the Federal Institute for Risk Assessment (BfR), Berlin. Boredom in animals that are kept under human responsibility is one of the greatest challenges for animal welfare. We therefore develop new concepts of social and environmental enrichment in order to counteract animal boredom in laboratory animals. In addition me and my group investigate individual differences, the interplay of cognition and emotion, and the animals' point of view with regard to better housing conditions and experimental designs.

End of September 2018 our application for the cluster of excellence Science of Intelligence got selected for funding within the German excellence funding program!
Understanding intelligence is one of the great scientic challenges of our time. Yet in spite of extensive research efforts spanning many scientific disciplines, our understanding of intelligence remains fragmented and incomplete. The Cluster of Excellence Science of Intelligence (SCIoI) aims to identify the principles of intelligence to fundamentally advance our understanding of intelligence as a whole – be it human, animal, individual, collective or artificial.
SCIoI will bring together researchers from different disciplines, such as robotics, artificial intelligence, neuroscience, philosophy, psychology, biology and human development. This allows to study, for example, how birds, mice and humans solve the same problems, such as mechanical puzzles. The obtained insights will then be transferred to artificial systems – robots or computer programs –, which are given the same challenges. This “synthetic approach” has three central advantages. Firstly, it forces researchers to check whether theories developed for biological intelligence are correct and useful. Secondly, it stimulates new hypotheses for the study of biological intelligence, because the inner workings of artificial systems can be analyzed with much greater detail than living organisms. Thirdly, it fosters a transfer of the obtained insights into technical applications. The approach of studying the same problems in a variety of different systems – animals, humans, robots and swarms – serves the central aim of the Cluster of Excellence Science of Intelligence: The discovery of general principles of intelligence.
