Research

Great advances in molecular biology, genomics and functional genomics open the way for a better understanding of regulatory mechanisms. These mechanisms interplay and operate at diverse levels (transcription and translation of the genetic material, protein modifications, etc.). They define large and complex networks, which in turn constitute a relevant functional framework to integratively study the control of cellular processes. To assess the behaviours induced by such networks, dedicated mathematical and computational tools are deeply needed.

In this context, our goal is to develop generic tools for the modelling and analysis of large molecular networks. For this purpose, we mainly rely on a qualitative modelling framework combining the generalised logical formalism and Petri nets. In a close collaboration with biologists, methodological developments are systematically challenged with real case applications, specifying and analysing models for the control of cell proliferation and differentiation.
