L-1.1: GENOMIC BASIS OF NICHE EVOLUTION

Population genetics & genomics with insects, genomics of population divergence, molecular ecology and evolution, adaptation and climate, epigenetic response to environment

I am interested in genomic mechanisms that shape populations, eventually driving population divergence. Such mechanisms can be influenced by extrinsic (abiotic of biotic interactions with the environment of individuals) or intrinsic factors (interaction of different genomic and molecular elements) or a complex interplay of both.
My current research focuses on evolutionary dynamics of Chironomus riparius, the non-biting midge or harlequin fly. I am investigating population genomic signatures of the different evolutionary forces, i.e. mutation, selection, drift, gene flow, and recombination. Moreover, I aim to disentangle the influence of climate factors, especially temperature (as extrinsic factors), as well as the influence of mobile genetic elements (as intrinsic factors) on the evolution of population divergence.

Polytene cromosomes


My approaches combine population genomics with individual genome scans and Pool-Seq data, common garden experiments, experimental evolution, and field work.
