My research interests involve numerically modeling physical phenomena, generally related to fluid and structural mechanics. In fact, most engineering problems require predicting the response of complex solid structures, which are either immersed on a fluid or in the inter-phase between fluids.

The following list gathers the most relevant projects in which I have been involved during my professional career. Looking forward, I plan to keep focusing on fluid-structure interaction and performance optimization, with applications to renewable energies, structural design, and additive manufacturing.
