Biography
Geoffroy Lumay is head of the "Soft Matter Experimental Physics and Complex Systems" group in the department of Physics of the Science Faculty. His research works articulate around two fields of Soft Matter Physics: granular material physics and colloid science. The common thread of his recent works in these two fields is the focus (i) on the effect of electromagnetic forces and (ii) on the influence of the surrounded fluid. In particular, the triboelectric effect in powders and granular materials, the behavior of grains in airflows and the effect of magnetic fields on super-paramagnetic colloids are studied experimentally. He is conducting these projects at the fundamental level and the obtained results are also valorized in the framework of more applied projects resulting in publications in more specialized journals, industrial collaborations and the creation of a Spin-off.
In his group, the strategy to study a physical phenomenon is based on the development of original experimental set-ups to obtain original experimental results. Afterward, physical models are proposed to describe the physical mechanisms and to extract the main parameters. If needed, numerical simulations are conducted in collaborations with colleagues to investigate parameters which are difficult to control experimentally.
