Research interests

The focus of my research is the genomic basis of niche evolution, speciation and local adaptation with closely related species pairs and intraspecific variation in land and freshwater snails, non-biting midges and extremophile molly fishes. We take an integrative approach: field studies, ecological and evolutionary experiments, comparative genomic approaches and experimental evolution. The ultimate vision thereby is to relate ecological differences functionally to their genomic basis.

Research interests
evolutionary genetics, evolutionary ecology, behavioural genetics  

I am interested in the adaptive potential of organisms to their environment. This may include abiotic factors, such as temperature, as well as biotic factors, such as the interplay within a social ant colony.

Niche evolution 
Closely related species, as well as different populations of one species, often occupy different niches and are thus adapted to different environmental properties. I’m interested in the adaptive potential of species to their environment, specifically to changing temperature and climate conditions. In this respect, a combinatory approach of studying both, proximate (phenotypic) as well as ultimate (genetic) traits is optimal. The combination of different methods (e.g. life-history trait determination, identification of selected genes) allows to draw conclusions on the proportion of phenotypic plasticity and evolutionary differentiation on the regulatory or structural level. As study organism I am working with the pond snail genus, Radix. Niche models have shown, that the distribution ranges between species (as well as populations) differ in temperature, as well as length of dry period.            

Behavioural genetics 
Social Hymenopterans feature a number of special traits, which clearly set them apart from all other animal groups. In ants, different worker castes and the queens develop from the same genetic background (polyphenism). In addition ant workers are further specialized on various tasks, from brood tending, over nest guarding to foraging. In some ant species behavioural caste differentiation is associated with morphological caste differentiation, however in other species monomorphic workers perform the different duties. I’m interested in the genetic mechanisms that lead to the development of the different castes as well as their differential behaviours. The genus Temnothorax is an ideal study system, as salvemakeing evolved several times independently, thus making it possible to investigate and compare the evolution of behavioural patterns in closely related species. In addition, the system allows to investigate co-evolutionary processes and local adaptation between closely related slavemaker and host species.

PostDoc, Member of Research Group 'Molecular Ecology'

I am an evolutionary biologist interested in molecular phylogenetics, genomics, systematics, biogeography and conservation. I use molecular tools in order to understand the evolutionary history of organisms, biodiversity origin, and molecular mechanisms at the population-species-environment interface. I have also experience working at Herbaria and I am passionate about natural collections.

My current projects aim to elucidate the demographic history of German wildcat (Felis silvestris silvestris) populations using whole-genome sequencing (WGS) and population genomics of European beech (Fagus sylvatica).
