Thèmes

My research mostly focuses on two complementary aspects: (i) the study of nano- (or submicron) scale processes such as those involving DNA (DesoxyriboNucleic Acid) and other molecular actors inside the cell nucleus and/or cytoskeleton, and (ii) the global dynamics and mechanics of living cells and the mechanisms of mechanical signal transfer from the cell exterior to the cell nucleus (back and forth). Both theses studies are now grouped under the title MECHANOGENETICS OF THE CELL.

The different experimental and theoretical approaches are illustrated in the figure below:

(a) Fluorescence staining of fibroblast cytoskeleton filaments: AFs and MTs (left), IFs (right). (b) Quantitative phase imaging of an adherent mesenchymal type cell. (c) Schematic of the nano-sensing tools for cell rheology. (d) Wavelet-based decomposition of signals [signals (top), color-coded time-scale decomposition (middle), WTMM chains (bottom)], and images [the original image (top right), the segmented image (top right)]. (e) Multi-network layer modelling with cross-linked (or uncross-linked) deterministic or stochastic molecular actors.

Curriculum vitae

CV_FArgoul_2017

Françoise Argoul received her PhD from the University of Bordeaux in 1986. She is a Director of Research of Centre National de la Recherche Scientifique (DR1 – CNRS – France). She manages a research program devoted to the experimental characterization of the mechanical and genomic response of cellular systems under external stresses, and to the role of mechanical and dynamical parameters on the modification of cellular regulation mechanims. This program combines experimental methods on single living cells (AFM, surface plasmon, phase contrast, quantitative phase imaging, high resolution fluorescence microscopy), modeling methods to understand the role of physical constraints on the route of cells to pathologies such as cancer and aging and analyzing tools for complex signals and images. After 13 years spent in Ecole Normale Supérieure of Lyon (Physics Laboratory) where she actively contributed to the creation of a transdisciplinary Joliot Curie Laboratory, she was offered in the fall 2015 the possibility to start a new project devoted to the mechanogenetics of cells and its alteration in cancer, in a brand new environment of the Laboratory Ondes et Matière d’Aquitaine.
