Curriculum vitae

I received a B.Sc. in Biochemistry and a M.Sc. in Microbiology, Enzymology, and Nutrition from the University of Nancy. In the course of this training, I developed a strong interest for pluridisciplinarity and I decided to develop my research activites in the fields of molecular biology and bioinformatics.

In 1998, I started my PhD thesis in the Laboratory of RNA Maturation and Molecular Enzymology headed by Christiane Branlant (Centre National de la Recherche Scientifique – Université Nancy I), while collaborating with the group of Alexander Bockmayr at Inria Nancy – Grand Est. I studied, both by experiments and mathematical modeling, the alternative splicing of the human immunodeficiency virus type 1 mRNA.

After having obtained my PhD in 2003, I joined Inria Grenoble – Rhône-Alpes as a post-doctoral researcher in the HELIX research group. In 2006, I have been recruited as a research scientist (chargé de recherche) at Inria. Now in the Ibis research group, I work on the mathematical modeling of biochemical regulatory networks in bacteria, in particular, the model bacterium Escherichia coli.

Research interests

Systems biology:

  • Mathematical modeling of biochemical networks: dynamical models (ODE and PLDE), constraint-based models, parameter estimation from heterogeneous experimental data
  • Analysis of gene expression and metabolism in bacteria: carbon starvation and osmotic stress response in Escherichia coli
  • Applications in biotechnology and food safety

I have given master courses in Bioinformatics and Systems Biology, in particular on the modeling and simulation of biochemical networks, at the Université Grenoble-Alpes, at the Institut National des Sciences Appliquées (INSA) in Toulouse, at the school of engineering in Physics, Applied Physics, Electronics & Materials Science (Phelma) in Grenoble, and in the Ph.D. Program in Computational Biology of the Instituto Gulbenkian de Ciencia in Lisbon (Portugal).

Organizational activities

In the framework of the French working group VICANNE, I organized with Hidde de Jong a meeting on integrated models of gene regulation and metabolism in Grenoble (May 2004). I organized with Eugenio Cinquemani a workshop on Identification and Control of Biological Interaction Networks (February 2011). I have been on the program committee of the Journées Ouvertes Biologie Informatique Mathématiques (JOBIM) 2007, 2008, and 2010, in the steering committee of the Seminar on Modeling in the Life Sciences SEMOVI (2007-), and in the scientific board of the Complex Systems Institute (IXXI, 2007-2015). I am a member of the Inria Evaluation Committee (2015-) and “référent chercheur” for the research centre Inria Grenoble – Rhône-Alpes.
