I have a broad range of interests in marine molecular microbiology but my current research is focussed on the network of interactions occurring between marine microorganisms. My research has three main axes:
- To generate new knowledge on carbon cycling and potential mediation of climate change. The microbial carbon pump is known to have an important role in carbon sequestration in the oceans but still little is known on how the food webs function.
- To understand how evolution in stable environments pushes free-living organisms to lose genetically-encoded functions in order to lower their costly maintenance. Therefore, microorganisms from different niches no longer compete; they collaborate by sharing vital functions.
- To discover novel natural products for future biotechnological exploitation. One of the biggest gaps found during the study of these natural products is determining their real function within their natural environment.
