1) Teleost Fishes (fossil & extant)

I am interested in understanding why speciation happens. I intend to understand the processes that form micro- and macroevolutionary changes. As far as possible, my students work based on a "total evidence approach". This means study of fossil and extant species based on data derived from skeletons, otoliths, dentitions, scales and, in the case of extant species, molecular sequences.
Research questions focus on evolutionary processes in the context of the geological history and environmental changes.
Groups currently under study:

  • Killifishes, with emphasis on Aphanius from Iran, click here for more information.
  • Gobiiformes, with focus on the evolutionary history
  • Cichlidae, with focus on the fossil record from East Africa (Kenya)

2) Kenya Project: Fish Fossils from Miocene Palaeolakes in the Central Kenya Rift and their Palaeoenvironmental Implications

We study the composition of the fossil fish fauna, co-occurring other fossils such as pollen and the sedimentary environment. Palaeontological and sedimentological data are used to reconstruct the Miocene palaeoenvironment and palaeoclimate changes (for details see Kenya Project).

3) Palaeogene–Neogene stratigraphy, biota and palaeoecosystems from the Paratethys and adjacent areas

Research questions include topics on biostratigraphy and chronostratigraphy, palaeogeography, regional geology, palaeoenvironment and palaeoclimate. See also Molasse Research (in German). Most Recent papers:
