Marine plankton form complex communities of interacting organisms at the base of the food chain, supporting biogeochemical cycles in the ocean and participating in climate regulation. Planktonic organisms are adapted to specific environmental conditions that limit their biogeography and ecology. However, we know little about how planktonic organisms interact to maintain perennial communities in the continuously homogenising oceans. Furthermore, the role of planktonic interactions in the realization of major biogeochemical cycles remains to be modelled for full integration of the biological component in ocean models such as PISCES. To address these challenges, we aim to develop computational tools to simulate the exchange of metabolites between marine microorganisms.
The main tasks of the project will be to:
- Model metabolic networks of organisms at the genome-scale using constraint or multi-objective programming approaches (main task).
- Integrate these models into co-occurrence graphs reconstructed via metagenomic data from recent oceanographic campaigns (Tara and Atlanteco) (main task).
- Numerically assess and predict the effects of multiple climate stressors on the state of ecosystems by identifying sentinel species sensitive to nutrient variations and having an impact on other organisms in the community (secondary task).
The candidate should have a PhD in (bio)informatics with skills in modelling of living systems. He or she should have skills in constraint modelling and an interest in issues related to microbial ecology. Experience in metagenomic data analysis is recommended but not required. Good writing and communication skills in English are expected, as well as the ability to work in a team.
The candidate will work at LS2N in Nantes on the site of the UFR Sciences et Techniques, within the ComBi team.
