RESEARCH TOPICS

The main activity of the ‘PHYGE” team (see more details at http://biopuce.insa-toulouse.fr/jmflab) deals with a systems approach of metabolic, genetic and genomic adaptation of fungal cells (yeast and filamentous fungi) to environmental conditions that are close to industrial constraints, with emphasis on carbon and energy metabolism, cell wall biogenesis and assembly, and genomic instability. In 2011, I was laureate of the 1st project call in ‘Investment of the future, with the a research project in Synthetic biology aiming at reconstructing new biological pathways capable to generate chemicals or synthons from agroressources. This project will be continued with the support of ADEME and industrial partner to reach the demonstration level (TRL7) in 2020. My research activity takes its roots from -and has applications- in Industrial microbiology/white biotechnology (bioethanol, biorefinery, flavours, probiotic /feed additives), agro-nutrition and pharmaceutical industries. Other financial support have been or are currently obtained from Europe commission (EU FP4, 5, 6 & 7), national agencies (CNRS, INRA, ANR), regional agencies (Region Midi-Pyrénées) and several industrial companies in the Agro-bioetch fields.

I was also head of a Bionanobiotechnology network in Toulouse that develops interdisciplinary researches on Biopatterning and integrated Biodetection from 2009 to 2014. This interdisciplinary activity with Bioengineers, physicists and chemists was hosted at the Institute for Advanced Technologies of Life Sciences at the Toulouse Canceropole. This research activity helped me to create DENDRIS (www.dendris.fr), a start-up which is exploiting Nanotechnology tools for molecular diagnostic and nanomedicine and holds several patents in biochips conception for diagnostic purposes.
