PhD, 2009, University of Vienna, Austria
        Title: Oxygen crises in the Northern Adriatic: effect on the structure and behaviour of the macrobenthos
        Jörg Ott (supervisor), Robert J. Diaz & Rutger Rosenberg (reviewers)

Research Interest 

  • Estuarine and coastal marine ecosystems
  • Benthic ecology
  • Assessment of anthropogenic impacts in the marine environment
  • Disturbance effects from the species level (e.g. behaviour, interaction, sensitivity, tolerance) to community and ecosystem level (biodiversity, structure, function, critical thresholds, recovery dynamics)
  • Experimental in situ work
