Pierre MILLARD

Researcher in Metabolic Systems Biology

Actual position and research subject

My research works aim at a better understanding of the organization, functioning and regulation of natural and synthetic metabolic systems at the cellular level, by using a Systems biology approach. This strategy combines experimental (growth phenotyping, metabolomics, 13C-metabolic flux analysis, etc) and computational (stoichiometric and kinetic modeling, statistics, etc) tools. In particular, I develop, validate and exploit explicative and predictive models, which integrate a broad range of functional data (stoichiometry, thermodynamics, metabolite pools, enzyme activities and kinetics, metabolic fluxes, isotopic measurements, etc) to investigate the control and regulation of metabolic fluxes. I then use this knowledge to understand the role of metabolism in the adaptation of Escherichia coli to its environment, and to design robust and efficient strains as cell factories for innovative and original biotechnological applications.
