My research interests cover a broad range of macroevolutionary topics from mass extinctions to biogeography and the development of quantitative methods.

Research themes

  • Biodiversity, biogeography and extinction in the time of Pangaea
  • Long-term ecological effects of mass extinctions
  • Linking past mass extinctions to the current/futue biodiversity decline(s)
  • Application of network methods to palaeobiological data
  • Testing the quality of the fossil record


I am always on the look-out for good students interested in research projects linked to my areas of research. If you have a project in mind, drop me an email.
