Research experience

 

Annie Viallat is ingénieur of Ecole Polytechnique (Paris, France). She received her PhD in Physics from the University of Grenoble (France) in 1987, working on PDMS/silica mixture and NMR. After a theoretical postdoctoral work on conjugated polymers in the Materials Department (UC Santa Barbara), she joined the Spectrométrie Physique lab (Grenoble) in 1989, studying polymer gels. Her research moved to biophysics and biomechanics in 1999. Since 2005, she is a group leader in the ‘Adhesion and Inflammation’ lab in Marseilles, interested in the dynamics of lipid giant vesicles, soft shells and blood cells in shear flow and in biomimicking capillary networks. Since 2007, she is at the head of a French National Consortium ‘Physics from cell to tissue’ (400 researchers) and organizes a three-days meeting every year.
