I am a Swiss postdoctoral researcher in the group of Prof. Dolph Schluter at the University of British Columbia in Vancouver (Canada).

I am fascinated by nature's diversity. In my work, I am thus trying to understand the evolutionary processes governing biological diversification. I am combining ecological and phenotypic information with genomic data to shed light on the processes of adaptive population diversification and speciation. My main empirical study system is the recent adaptive radiation of threespine stickleback fish. I study wild stickleback populations inhabiting ecologically distinct environments, such as lakes and streams, or lakes that differ in the presence of a single competitor (sculpin fish). In my ongoing work, I am also conducting experiments in (semi-)natural environments with wild and artificially crossed stickleback. My empirical insights stimulate and inform my theoretical work. I have a particular interest in using computer simulations to better understand the genomic consequences of selection.
