Wild populations are increasingly exposed to demographic decline and fragmentation, making inbreeding and its consequences a central problem in evolutionary biology and conservation. We address this using one of the most comprehensive datasets available for any vertebrate population: a longterm field study in Switzerland of more than 20,000 wild mice that vary naturally in degree of inbreeding. We aim to quantify inbreeding effects on behaviour, reproductive output, survival and morphology and relate these to genetic loci. The PhD project is embedded in a collaborative framework with network scientists and evolutionary biologists at the University of Zurich and at Columbia University.

We are seeking a highly motivated PhD student to join our research group at the University of Zurich to examine the phenotypic and genetic consequences of inbreeding in a wild mammalian population.

• analyse large-scale phenotypic datasets (behaviour, life history, morphology)
• perform animal experiments on inbreeding
• develop and apply statistical models
• collaborate across disciplines (behavioural ecology, network science, genomics)
• contribute to high-quality publications

• fascinated by fundamental questions in evolutionary biology
• MSc (or equivalent) in evolutionary biology, ecology, animal behaviour, or a related field
• training in quantitative genetics and behavioural ecology
• evidence of analytical ability and scientific independence
• strong quantitative skills, R programming, experience with large datasets
• project management, teamwork, scientific communication and organisational skills
