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.

More precise scopes are listed below, together with the resulting publications ([A..] = journal articles, [Pr..] = proceedings articles, [Ch..] = book chapter, [E..] = editor work, [Doc..] = code documentation).

You may also check the Scopus details (ID: 36559174600), as well as my Orcid page for more background information.
