Présentation

My background is in liquid physics studied in Paris. After a first research experience on granular flows in hoppers in the group of Pr. E.Clément in Paris in 1997, I did my PhD on eolian transport of granular materials under the supervision of Dr. A.Valance and D.Bideau in Rennes (2002). I spent my first postdoctoral time in the Liphy lab. in Grenoble working with Dr. T.Biben and Dr. C.Misbah on the modelling of vesicle dynamics under flow with applications on blood flow rheology (2003). I then joined the foam physics group of Pr. D.Weaire in Trinity College Dublin where I worked on foam rheology (dilatancy) in possible relation to the onset of convective instability in foams (2004). Since 2005, i worked in IRSTEA then INRAE on particulate flow processes and transfers with applications in environment (spreading technologies in agriculture (TSCF lab), rockfall modelling in mountain areas (ETNA lab)) and chemical engineering related to refrigeration applications for food or bioenergy (FRISE lab) as in grain storage or heat exchange technologies. I appreciate to do fundamental science on technologically relevant systems with sometimes unexpected results... More generally, my recent work is part of a more general approach which intends to revisit the different process chains encountered in the agriculture and agro-food sector in the perspective of the necessary energy transition.
