Find a presentation of my research activities on the Flows for material processing page. My main concerns are acoustic streaming flows generated by ultrasound beams in liquids, solidification of metallic and semiconducting alloys, and non-newtonian film flows stability.

I also teach fluid mechanics, experimental methods and system thermodynamics in the mechanical engineering department at INSA Lyon.

You can find my publications and keywords on HAL but also here
