Research interests

  • Temporal shifts and spatial variation in traits of marine fish communities
  • Effects of environmental and anthropogenic changes on the functional biodiversity of marine communities


  • Expansion of a trait database for demersal fish in the North Sea
  • Trait-based times series analysis of shifts in North Sea fish communities over distinct spatial scales
  • Development of a statistical method allowing for integration of data from different surveys and sampling protocols into a combined analysis
  • Investigation of interactions between benthos and fish communities as a consequence of changes in the ecosystem
