Hecq Jean-Henri
Dr, FNRS Senior Research Associate


Jean-Henri Hecq is a senior scientist with strong expertise in marine plankton ecohydrodynamic and modelling. Current interests focused on Antarctic and Mediterranean coastal areas and concern:

  • the control of marine plankton biodiversity and fish recruitment by environmental factors,
  • the interactions between pelagic biodiversity and ecosystem functioning,
  • the improvement of conceptual and numerical ecohydrodynamical models of the ocean pelagic ecosystem in view of determining the stability of biotic assemblages, their sensitivity to the environmental constraints and especially the response to climate changes.

In the Southern Ocean, Jean-Henri is mainly involved in projects focusing on the Terre Adelie area.
