I am a postdoctoral researcher studying organismal diversification, especially in the context of adaptive radiation. Together with Patrik Nosil I investigate patterns of genomic divergence across the adaptive radiation of Timema walking-stick insects. In collaborations with Ole Seehausen and Walter Salzburger, I work on the ecomorphological and genomic evolution of cichlid fishes.

SNSF Sinergia grant is starting Last November, we received the great news that our application for an interdisciplinary Sinergia grant was approved by the Swiss National Science Foundation, and the project starts already this month. Over the next four years, our large team of collaborators will investigate Lake Victoria's prehistory with a focus on how the diversification of haplochromine cichlids interacted with changes in the ecosystem. You can find more information on the SNSF's project database (link).

Practical in Aquatic Ecology & Evolution  During this year's four weeks long intensive practical we will investigate the fish community composition in Lake Constance though time using sediment cores.

Coring expedition to Lake Victoria Just returned from the shores of Lake Victoria, Tanzania, where a team from Tafiri, Uni Bern (IPS and IEE), and Eawag retrieved a large set of sediment cores covering the entire life time of the modern lake (i.e. ~15000 years). A great team working very hard and some luck with wind conditions made this possible. The expedition was funded by an University of Bern Strategy Grant. 


The ancestors' tale. During a stay at the Ancient DNA facility at the Centre for Ecological and Evolutionary Synthesis of the University of Oslo, I succesfully extracted fish DNA from several thousand years old cichlid fish bones. I am going to use this approach to study the adaptation to changing environments through time in these fishes. 

Rocks and bugs in California. From April to June 2015, I collected Timema stick insects together with Patrik Nosil's group from Sheffield, UK. Fortunately, Timema and their host plants seem to like boulders, too. From the samples we hope to learn just how cryptic these insects are on their host plants, and if that changes with the number of host plant species a given population of insects uses.
