Séminaires Doctorants

publié le , mis à jour le

De manière variable (en général une fois par moi), le vendredi de 16 à 17h, deux doctorants ou stagiaires présentent leurs travaux (ou ce qu’ils aiment) en une quinzaine de minutes (max 30 min).

Les séminaires sont ouverts à tous, sont toujours suivis d’un (ou des) gâteau et parfois de boissons désaltérantes (gentiment amené par des doctorants ou des stagiaires, n’hésitez pas à retrousser vos manches).

    (1) Failure of leaf hydraulic networks. (2) Adaptive Optical Microscopy to Study Tissue Dynamics in Spheroids

    Résumé : - Diane Bienaimé (DyfCOM)
    Water under tension, as can be found in several systems including tree hydraulic networks, is metastable. In this case cavitation can spontaneously occur under water stress. The nucleation of a bubble and its propagation into the network prevent the embolized vessels from transporting water. We investigate the dynamics of such networks failure in different leaf architectures.



    Several experiments have shown that a mechanical stress hampers the growth of a Multi-Cellular Tumour Spheroid, but it remains unclear by which mechanism these stresses inhibit cell division. It is suspected that the Extracellular Matrix plays a role in this mechanosensitivity.
    Using Fluroescence Correlation Spectroscopy (FCS) we can probe the dynamics of the Extracellular Matrix with high spatial resolution. However, spheroids heterogeneities induce optical aberrations that make FCS measurements unreliable beyond the first layer of cells. Therefore, we will use a two-photon microscope equipped with an Adaptive Optics to overcome these aberrations
    This talk will focus on the principle and construction of a Two-Photon AO microscope for this study.

    PhD Seminar

    Résumé : Studiing bones via X-Ray by Mariana
    Bone tissue is a highly heterogeneous hierarchical composite material. The nanoparticles organization and structure in bone have been identified as potential markers of bone quality and diverse pathological conditions. Nanoscale bone organization study by transmission electron microscopy and synchrotron nano-beam SAXS and WAXS will be presented.



    Water intrusion in hydrophobic Nanoporous materials by Loic
    In this first seminar I will introduce the scientific and applicative background surrounding the high pressure intrusion of water in hydrophobic pores of nanometer radius. Such a confined water can be found inside and around proteins and in materials for energy storage. I will first summarize the current understanding, its limitations, then the high pressure experiments and molecular dynamics simulations on which I am working on. We will see how the chemical control of materials allow us to probe the physics of confined water.

    [PhD Seminar] ’Scientific creativity : What, Why and How ?’ Darja Dubravcic

    Résumé : Abstract :
    Today more than ever, we scientists are expected to be innovative, creative and authentic so that they can produce novel ideas, publish in prestige journals, get grants and be entrepreneurial. But, no one ever thought us what creativity is and how to develop it. On the other side we were thought physics, mathematics, chemistry and biology. All that you need to think like others, but not different from others. Scientific studies show that creativity can be learned just like any other discipline, and that using creativity techniques helps us have more innovative ideas.
    During this presentation I will dispute the dogma that you are born creative and that great ideas are reserved for genius minds. I will also present a few creativity techniques that can help you think differently and have more and better ideas.

    Active substrates to decode mechanotransduction

    Résumé : Active substrates to decode mechanotransduction.
    Mechanotransduction is the ability for cells to probe their mechanical
    environment and react to it, biochemically and mechanically. It plays as
    major role in development, wound healing, sensory systems, as well as in
    bone disease and cancer.
    Here I will present how we intend to decipher the transfer function of
    cells instead of studying the (far too) many pathways involved in
    mechanotransduction. In order to control the mechanical environment of
    cells we use active substrates, that also allow us to read the
    mechanical response thanks to TFM (Traction Force Microscopy). Then we
    use FRET (Forster Resonance Energy Transfer) Microscopy to read the
    biochemical response of cells.
    And I may talk about the effects of ultrasounds on cells...
