Area of interest
I’m a biochemist and enzymologist interested in the dynamics of metabolic fluxes and energy regulation in photosynthetic organisms (plant, algae’s). Living systems have evolved sophisticated molecular mechanisms to prevent shortage or over-accumulation of metabolites upon variation in the environmental conditions and I specifically focus my attention on integrated short-term controls occurring in a matter of minutes [1]. A thorough understanding of the function of molecular mechanisms described in vitro requires the integration of biochemical data into quantitative mathematical models to carry out simulations.

Another challenge in metabolism is the representation of the wealth of molecular data accumulated for more than 50 years of research into a comprehensive whole. The extreme imbrication of the processes results in an impossibility for the human mind to capture metabolism behaviour at a single glance. To overcome this caveat I’m involved in the development of a specific visual Web Interface to explore the metabolism of the model photosynthetic organism A. thaliana at the molecular level (in collaboration with the EDyP team (BGE laboratory at our institute, CEA-Grenoble) for the bioinformatics and with team ChloroGenesis, and team Dynamic of metabolism in our laboratory). This friendly visual web interface (soon available to the public) will facilitate research communication, generation of hypotheses, knowledge acquisition by students, and will help biotechnologists to rationally choose target enzymes to knock-out or overproduce.

[1]Stocks of metabolites are generally small (1-10 million molecules in a chloroplast for example) compared to the fluxes for their transformation (1-10 million per seconds for the fastest processes). In the absence of efficient and fast regulatory processes (operating in a matter of seconds) oscillations and chaotic behaviour would be encountered by living systems, limiting growth (shortage) or leading to death (over-accumulation of toxic metabolic intermediates).
