Main research interests

All the work I have done since 2003 is experimental. I have been mainly using optical and acoustic techniques to perform time or spatially resolved studies of creeping flows of different complex fluids, namely: granular materials, carbopol gels, giant micelles solutions, etc. The main achievements of my PhD work, has been first to caracterize the intermittent dynamics of gas bubbles rising through a column of a simple yield stress fluid, and second, to minutely describe the creep motion of a granular pile induced by controlled variations of (real) temperature. As a Post-Doc since September 2009, I apply my knowledge on both acoustics and complex fluids to unravel the fluidization process of yield stress fluids (namely Carbopol and Carbon black gels) by mean of a one dimensional ultrasonic velocimetry technique which gives access to velocity profiles simultaneously to rheology. Since October 2011, still as a Post-Doc I am performing two particle interfacial microrheology of protein films at the Weeks' Lab where my current focus is to measure very low surface viscosities.

Teaching interests

I assist graduate students in preparing the "Agrégation", a french national competitive exam that enables the elected ones to obtain a position as undergraduate teacher. The applicants prepare a selection of roughly 150 topics in physics and chemistry over a year (undergraduate level). The final exam takes place over 3 days and consists in 3 lectures of 50 minutes each randomly selected including several experiments. I wrote several contributions available in the teaching material section of this website.
