I am a chemical ecologist specializing in marine microbial phycospheres. My primary emphasis is on microalgae, a pivotal component within aquatic food webs. Specifically, I study harmful species such as dinoflagellates, whose proliferation is escalating in many coastal areas in response to current modifications of marine ecosystems. I aim at understanding how the exchange of metabolites between these toxic microalgae and other microbial species contributes to their ecological success and toxicity. I am particularly interested by airborne toxicity resulting from the release of algal metabolites into the atmosphere. Ultimately, my research ambitions to provide stakeholders with the essential knowledge for managing harmful algal blooms. My research is multi-disciplinary and involves oceanography, organic chemistry and ecology. I use original experimental designs in chemical ecology and sea-air coupling, combined to state-of-the-art mass spectrometry, metabolomics and molecular modeling.
