Research Interests


I moved to Mainz (Germany) to study Biology with Psychology as minor. I did my Diploma thesis on cooperation among rats in the group of Prof. Michael Taborsky at the University of Bern (Switzerland). During my subsequent PhD position, I continued my research on rats trading help. Currently, I am a postdoctoral researcher investigating the social life of rats before moving to St Andrews this fall. My research interests lie mainly in the field of animal behaviour, in particular in an understanding of the mechanisms of complex social life. Additionally, I have always been interested in applied issues like animal welfare.

Current Research Area

During my studies I was especially fascinated by the evolution of cooperative behaviours. Animals cooperate by benefiting others at on own costs. Indeed, on the first view cooperativeness seems to contradict Charles Darwin’s theory of evolution. While thinking about eusocial insects, Darwin stated: „…one special difficulty, which at first appeared to me fatal to the whole theory of evolution…“. However, Darwin also offered a solution to this problem when stating in “The origin of species” (1859) that the problem „…disappears, if one remembers that selection can also act on the family, not only on the individual…”. However, cooperation frequently takes place also between unrelated individuals. Possible explanations are far less studied. One mechanism that maintains cooperation is reciprocity. Here, an individual helps a partner because this partner previously helped the first.

In my PhD I studied mechanisms underlying reciprocal helping behaviour in undomesticated wild-type Norway rats (Rattus norvegicus). Rats live in big colonies and show a wide range of social behaviours such as food sharing, huddling or allogrooming. In this highly social species, previous lab studies have shown that the propensity of a rat to cooperate is dependent on its previous cooperative experience. I investigate reciprocal exchanges of different services both in a two-player food exchange task (simulating an iterated Prisoner’s dilemma game) and under more natural conditions. In addition, I am interested which social factors influence reciprocal trading.
