PhD Position in Evolutionary Ecology

100%, Zurich, fixed-term

Our group at ETH Zurich has a position for a PhD student to study co-evolutionary dynamics in the “killer yeast” model system.

Project background

The “killer yeast” system features eco‑evolutionary interactions among plants, animals and fungi, as well as viruses. The core of the system is the winemaking yeast Saccharomyces cerevisiae, which is mostly found in ephemeral fruits. Yeast modify their niche to drive the coevolution of mutualism between themselves and Drosophila flies. Yeast is also used as a host by various double stranded RNA viruses. Certain dsRNA virus combinations (dsRNA L-A virus and M satellite dsRNA) convert the yeast to a killer phenotype providing the yeast strain with a competitive advantage over other coexisting strains. The actors in the killer yeast system - S. cerevisiae, dsRNA viruses and Drosophila are all excellent research models in their own right with well-established population genetic, -omic and ecological toolboxes. The system is suitable for both field and laboratory studies, which are expected to be part of the developed PhD project. We invite applications from candidates who are interested in studying the coevolutionary dynamics and population ecology of the interacting species, whilst focusing on topics that are not only of broad interest within fundamental research, but also highly relevant to more applied fields (e.g. winemaking).

Job description

The position is for four years, during which the PhD dissertation at ETH Zurich is expected to be completed. The PhD candidate will be supervised by Dr. Claudia C. Buser and Prof. Jukka Jokela of the Aquatic Ecology group at the Institute of Integrative Biology at ETH Zurich.

Your profile

We are looking for a highly motivated, enthusiastic and independent person with a passion for science. Candidates for this position should have a strong interest in evolutionary ecology and microbiology. They should be open to learning new skills in experimental hypothesis testing, population genetics and evolutionary biology. Formally, candidates need to hold a MSc degree in biology, environmental sciences or another relevant field.
