Microbiology: Fermentation process (small and high throughput) in batch or chemostat with S.cerevisiae and E. coli. Metabolic engineering. Synthetic biology. Metabolomics and fluxomics.
Biophysics: NMR, mass spectrometry and chromatography (GC‐MS, GC‐TOF, LC‐MS‐MS, DIMS‐MS), fluorimetry.
Mathematics: Statistical analysis, Machine Learning, modelling, R, and Matlab.
Molecular biology: PCR, cloning, transformation.



My research aimed at developing innovative and original biotechnological processes using E. coli (or other) as a cell factory for upgrading biomass for biofuels, power and/or bioproducts. Specifically, I try to understand the organization and functioning of natural and synthetic metabolic networks at the cellular level using metabolomics and fluxomics. I then use this knowledge to design and optimize new synthetic metabolic pathways.
