I study granular materials and pattern formation processes using a combination of numerical simulations and laboratory experiments. During my masters I started studying granular materials through an internship in a metamaterials laboratory at university of Amsterdam where I investigated the behaviour of a packing of auxetic grains. I spent six months in PoreLab during another internship during which I studied frictional fingers in a gravitational potential. I defended my PhD in July 2024 at the physics laboratory at ENS de Lyon in France. During my PhD, I described and characterized a surface instability that leads to the formation of ripples when a solid is dragged across a granular bed, and I developed an expertise in discrete elements method simulations of granular materials. I used my simulations in a collaboration with a Brazilian professor in a research project involving the flow of a mixture of magnetic and non magnetic grains on an inclined plane, during which we characterized the aggregation and segregation of the magnets. I started my postdoc in October 2024, and I am resuming previous experiments and simulations on frictional fingers, as well as other research projects involving magnetic grains.
