ENVICOPAS - Impact of Environmental Changes on Coastal Pathogens Systems

In the last decades, massive mortalities of oysters are more frequently reported and have beenassociated with bacteria of the genus Vibrio. Some of these bacteria are potentially human-pathogenic and can cause, for example, gastroenteritis, wound or ear infections. An increasing number of human infections due to Vibrio spp. in the North and Baltic Sea has been reported since the mid 1990s. It is anticipated that under global warming conditions, the risk of the occurrence of these (human-) pathogenic bacteria will further increase.

Within this interdisciplinary project, the aim of my PhD is to predict the effect of environmental changes (e.g. temperature changes) on pathogen dynamics in coastal environments. Particularly, the influence of changing environmental conditions on

  1. the spatial distribution of pathogens due to hydrodynamic flows,
  2. the population dynamics of Vibrio spp. in the seawater and
  3. pathogen transmission between oysters

will be studied with a coupled biological-hydrodynamic model. This will help to evaluate the potential alteration of the disease risk in the context of climate change and environmental disturbances.

Scientific interests

  • Theoretical ecology, especially eco-epidemiological modelling and population dynamics of host-parasite systems
  • Oceanography, especially unstructured-grid ocean modelling and hydrography of the North Sea
  • Aquatic diseases, especially the spatial dispersion of pathogens and impact of climate change
