I have broad interests in evolution, speciation genetics, phylogeography, biodiversity, molecular ecology, behavior and systematics, especially (but not only) of vertebrates. Science history tells us about the transitory nature of some scientific knowledge. Regarding the formation of new evolutionary lineages, I think that future research will reveal a much greater role for reticulate evolution enabled by interspecies/interpopulation interactions and hybridization in animals. This will change our insights into the diversity of genes, genomes and phenotypes, and their relation to environment and evolution.
To understand the processes that generate biodiversity, my research includes organismal, genetic and genomic topics to examine evolution through hybridization and allopolyploidization in a phylogenetic framework.
I am addressing these questions in selected vertebrate systems (mainly Palearctic frogs) on different spatial and temporal scales. This research also touches a variety of exciting evolutionary questions as the consequences of genome and gene duplication, evolutionary genetics of hybridization with the interplay of two or more foreign genomes in one nucleus and one organism, the evolution of sex and recombination, the occurrence or absence of meiosis, crossing over and recombination, mitochondrial evolution as co-evolution with the nucleus, hybrid fertility and fitness, and ultimately hybrid speciation and evolution. This stimulates pleasant interdisciplinary collaborations.
The major research topic of my current position with Prof. Nicolas Perrin is molecular genetic research on the sex determination systems in hylid and bufonid frogs. We have developed a phylogeographic framework (including the discovery of so far unrecognized Hyla-lineages) that will allow studying and dating the molecular evolution of sex-linked markers in several taxa.
