Research interest
Biodiversity and its origin, the speciation process, are the focus of my research interest. Although since Darwin’s “The origin of species” we know much about how species split and diverge, we have only recently started to connect speciation research and population genetics from an empirical perspecitve thanks to genome-wide data obtained with next-generation sequencing techniques.
Therefore, I am interested in the interface of evolutionary and population genomics and macroevolutionary processes, in particular in adaptive radiations. What factors in the genome are constraining or promoting speciation at different stages of the process? How does genomic architecture affect a propensity for speciation? How is variation in the genome influenced by population history or hybridization and what role does it play in speciation and in particular in adaptive radiations? And in a more holistic approach, which processes contribute to what extent to the emergence, maintenance or brake-up of separate evolutionary lineages and consequently of biodiversity?
I am using Three-spined Sticklebacks and Lake Victoria Cichlids as model systems to address these questions. Both are known for their unusually high rates of speciation in adaptive radiations. Various stages of speciation at different time scales are present among these model systems, what makes them perfectly suited to investigate the evolution of organismal diversity in adaptive radiations.
