    Static and dynamic theories of the glass and jamming transitions
    The glass and jamming transitions are two distinct mechanism by which atomistic (for the glass transition) and granular (for the jamming transition) systems acquire rigidity on a laboratory time scale. Although the glass and jamming physics are quite old subjects, the development of quantitative theories has (...)

    Mechanical amplification in the inner ear
    The ear is not a passive receiver of sound ; an active process instead endows our hearing with its remarkable features. The active process amplifies sounds by more than a hundredfold, greatly enhancing our sensitivity to weak stimuli. The ear's intrinsic amplifier additionally tunes our responsiveness to specific (...)

    The hidden hallmarks of nonequilibrium
    Systems with disparate timescales are ubiquitous in physics and biology. Efficient modeling requires to restrict the description to the slower degrees of freedom by means of a systematic, controlled elimination of fast variables. I will discuss this general issue in stochastic systems with multiple timescales. I (...)

    Reactive liquid interfaces
    Our goal is to control the properties of liquid interfaces (stability of a foam, spreading of a liquid on a surface) by using ‘reactive' amphiphilic molecules. I will give two examples : Photo-responsive bubbles, films and foams. We use surfactants which change their shape under UV light. The light intensity (...)

    Probing the target search of individual DNA-binding proteins in mammalian cells
    For many cellular functions, DNA-binding proteins (DBPs) need to find specific target sites in the genome. Facilitated diffusion (FD), namely the combination of one-dimensional motion along non-specific DNA and three-dimensional exploration, is the dominant model for the target search (TS) of DBPs. Yet, this model (...)

    Real time control of gene expression in yeast

    Rigidity transition in amorphous media
    Contrarily to cristalline solids, amorphous media (glasses, emulsions, granular media, suspensions, foam, etc) do not present any long range translational order. However, they can resist shear and therefore behave mechanically as solid materials. To make them flow as a liquid, one has, depending on the material, (...)

As far as drug delivery is concerned, the shape of the carrier is believed to have a strong influence on the biodistribution and cell internalization. Polymersomes can be submitted to an (...)

    Flow of polymer solutions in porous media : rheology, slippage, confinement and turbulence
    Polymer solutions are used to control biphasic flows in porous media since by increasing the viscosity they tend to prevent fingering and to smooth the permeability heterogeneities. However, several additional phenomena need to be considered, such as non-linear rheology, elasticity and violation of the no-slip (...)

General recommendations for the speakers

The audience is often heterogeneous - because of the wide range of scientific topics covered in the lab - so planning a talk for a broader audience would be preferred. The seminar is in English, and speakers are thus invited to prepare their slides in English.

The seminar starts at 11:30 AM. The speaker is asked to arrive in the lab at least 15 minutes in advance to set up their computer. The talks last typically 45 minutes, and are followed by a discussion time.
