I'm studying through numerical simulations how natural materials (soil, rock, ..), or the structures built thereof, deform under loads. Since most natural materials are made from grains (sand being a typical example), I usually perform these numerical simulations looking at a collection of interacting particles. Applications of my research lie in the field in Civil Engineering, e.g. for hydraulic structures such as dams.
