Research Interest

Natural selection often reduces variation, as it favors the survival of the fittest. Understanding how evolution has generated the marvelous diversity that surrounds us thus presents a challenge. Much of my scientific work is motivated by the question how selection can create and support biological diversity. This theme is at the core of my PhD thesis work on sexual selection and sympatric speciation and also inspires my recent work on intraspecific behavioural variation and animal personalities. With Michael Taborsky, I work on models for the evolution of cooperation through generalized reciprocity. I address my research questions with various theoretical tools: individual-based computer simulations, phenotypic modeling approaches (game theory and adaptive dynamics) and multilocus population genetics.

Opportunities for student projects

I welcome (MSc-)students who wish to learn more about theoretical modeling and are interested in working on one of the following research topics:

· The evolution of cooperation through generalized reciprocity

· Ultimate explanations for behavioral syndromes and animal personality

· Animal communication during aggressive interactions

· Sexual conflict and the evolution of sex-determining mechanisms

Please contact me for detailed information about these opportunities.
