Kiesgen de Richter
Associate professor in Physics of granular media
Junior IUF member (Institut Universitaire de France)
Head of the "Powder and suspension flows" team
Since 2009, I am tenured associate professor (HDR) at the LEMTA laboratory, and a lecturer at the Faculty of Science. I am head of the "Powder and suspension flows" team. My research activities are mainly concerned with the physics of granular media, powder technologies and rheology of complex flows. I am the currently the coordinator of the international research project "Pastflow" co-funded by the french national research agency (ANR) and the german research foundation (DFG) / 2020 - 2023 / 360 k€. I also managed a fundamental competitive European program, indeed I was the coordinator of the European Interreg VA "PowderReg" project involving 5 universities of the Great Region in order to study the "transport, storage and forming of industrially relevant powders" / 2017 -2021 / 6 M€.
Since October 1st, 2021, and during a period of 5 years, I am a Junior IUF member (Institut Universitaire de France).
I had the pleasure to attend the 10th International Conference for Conveying and Handling of Particulate Solids CHoPS in Salerno (Italy) from July 5 to 9. My PhD student, Ghita Marouazi, was able to present her work "Experimental study of granular heap flow under vertical vibrations". Thanks also to the organizers for giving me the opportunity to be the chairman of the session "Mixing and Segregation".
A new video "Osez l'Europe" and an article on the University website have just been published about the "PowderReg" project!
Have a look at the video in the Research overview tab, "PowderReg project" section.

I will be in Belgium at the GRASP laboratory as an invited researcher from April 25 to 29. I will also take a course with Professor Scott Russel WAITUKAITIS (Institute of Science and Technology, Austria) on the subject "From rabbits to planets: the enduring mystery of contact electrification". Thanks to the GRASP team for inviting me.
