Missions

Applications are invited for a 2 year Postdoctoral position in the Photosymbiosis team in the Cell and Plant Physiology Laboratory. The postdoctoral researcher will be part of the ERC consolidator project SymbiOCEAN, which aims at investigating photosymbiosis in the marine plankton at the subcellular, molecular and ecological levels. We are seeking a highly motivated, enthusiastic and talented scientist with skills and knowledge in bioinformatics and molecular biology.
The successful candidate will develop and lead a research project to study the metabolic connectivity between the host and the microalgae in photosymbiosis. The candidate will particularly focus on the sugar transporter candidates of symbiotic microalgae (Phaeocystis) that are potentially involved in carbon export to the host (Juery et al ISME journal 2024, see below). This will involve fieldwork for sampling, different bioinformatic approaches (genome mining, phylogeny) and molecular biology techniques (RT-qPCR, immunolocalization). This project will be conducted in collaboration with team members (engineers and PhD candidates) and different national and international institutes. To know more about the project´s topic, some publications are available on Google Scholar and below our recent publication linked to this project.

Activités

- Develop a research project to study the transporters involved in carbon flux in planktonic photosymbiosis with the microalga Phaeocystis
- in silico characterization of transporters, genome and transcriptome mining, design of primers and antibodies, phylogenetic reconstruction.

- Immunolocalization of transporters coupled with fluorescence microscopy, and/or RT-qPCR to assess expression level of transporters

- Fieldwork for sampling symbiotic organisms

Compétences

- PhD (or final stages of PhD) in a relevant biological subject (e.g. microbial ecology, genomics, plant biology).
- The candidate should have a good academic track record, and solid background and research experience in bioinformatics and molecular biology techniques.
- Knowledge and research experience in microalgae/plants and marine protists, as well as fluorescence microscopy, would be considered an advantage.
- Excellent written and oral communication skills and proficiency in English are required. French is optional.
- The candidate should have good interpersonal skills and ability to work independently, but also to interact well within a young international research group.

Contexte de travail

The postdoctoral researcher will be employed by CNRS, and be part of the Photosymbiosis team (photosymbiosis.com) of the Cellular and Plant Physiology Laboratory (UMR 5168 - CNRS -CEA - Univ. Grenoble Alpes - INRAe) in Grenoble (France). The work will be performed under the supervision of Dr. Johan Decelle, who is part of the EMBO Young Investigator Program The team's projects aim to better understand the functioning of unicellular photosymbiosis by combining sub-cellular imaging, photophysiology and molecular biology. This position is part of an ERC consolidator-funded project (SymbiOCEAN) led by the Photosymbiosis team. Numerous interactions and synergies will take place with national and international partners.
