Research interests:

Development of theoretical and experimental methods and software for the linear and non-linear hydrodynamic analysis and design of individual or multiple waterborne and / or fixed marine structures. Hydrodynamic study and design of devices for oceanographic applications (oceanographic floats, autonomous underwater recorders - AUV's, gliders). Development of experimental and numerical methods and related software for the static and dynamic analysis of anchoring systems, their optimal design and the hydro-mechanical analysis of anchored marine structures.
Numerical and experimental analysis and estimation of the performance of individual and / or interfacing wave energy recovery devices. Numerical and experimental analysis of the coupled hydro-aero-elastic behavior of floating wind turbines, floating wind farms and offshore structures for the coupled exploitation of wind and wave energy.

Research experience:

Participation in 51 research and development projects, 35 of them as Project Coordinator or Scientific Coordinator. He is the author of more than 140 scientific publications in international scientific journals, conference proceedings, books and book chapter
