Researcher in Microalgae Ecology

IFREMER - French Research Institute for Exploitation of the Sea

New Caledonia, France

Job profile

Placed under the supervision of the Director of the Lagoons, ecosystems and sustainable aquaculture in New Caledonia Unit, the researcher will carry out research using his/her expertise in phytoplankton ecology and biology in order to characterize marine microalgae community composition and diversity in New Caledonia. The researcher will interact more generally with other researchers from the LEAD-NC team working on aquaculture development.

General areas of responsibility (principal missions)

Integrated in the LEAD-RBE research unit, the New Caledonian Ifremer station is situated in Nouméa, the team develops research on bio- and chemo-diversity of phytoplanktonic communities from lagoon ecosystems, in relation with the nutrition of cultivated species (in particular shrimp farming). Overall, the LEAD-NC team aims at understanding the interaction between diversity and adaptative mechanisms in phytoplanktonic communities facing global change and anthropogenic pressure.

Principal activities

He/she will:

  • Be the scientific Manager of the Ifremer research team of the microalgae laboratory in Ifremer (LEMA), mutualised with the l'Agence de Développement de la Nouvelle-Calédonie (ADECAL). Propose, organize and manage research projects developed around the ongoing research program Phytoplankton cultivation in New Caledonia (AMICAL), and related local, national and international research projects;
  • Identify and isolate phytoplankton species showing an interesting biochemical composition and test its potential as food source for cultivated species (shrimps and fish), in collaboration with physiologists working on those species;
  • Study the metabolic impact of environmental condition and genetic selection on the species of interest;
  • Study the impacts of potential anthropogenic pressures on the lagoon environment via microalgae diversity;
  • Write scientific communications and publications showcasing the results obtained;
  • Participate in the scientific animation on “microalgae” in New Caledonia, in collaboration with the University of New Caledonia and the IRD.

Profile and expertise sought

Initial training

  • Degree: PhD in Science: biology, biochemistry and phyto-ecology, aquaculture nutrition.


  • Professional experiences and a postdoctoral fellowship is preferred.

Personal qualities 

  • Team work and team management;
  • Organization and a sense of initiative;
  • Scientific writing in both french and english;
  • Scientific rigor. 

Specific knowledge

  • Excellent knowledge in the biodiversity (taxonomy), physiology and chemodiversity of marine phytoplankton;
  • Ability to characterize interactions between biotopes and microorganisms communities;
  • Knowledge of the valorization options for active molecules (nutrition, cosmetic, health…);
  • Marine aquaculture;
  • Project managment;
  • English and French.
