1. Mechanics: Direct and inverse wave scattering and radiation problems in acoustics, electromagnetism, elasticity, thermoelasticity and strain gradient elasticity. Wave propagation in waveguides, composite, non-homogeneous materials and biomaterials. Non-destructive Testing through wave propagation phenomena (Acoustic Emission, Ultrasonics, Acousto-ultrasonics, Laser scattering). Fracture mechanics. Homogenization techniques. Mechanical vibrations and vibration isolation. Mechanics of materials and biomaterials with microstructural effects.
2. Biomedical engineering. Computational Mechanics: Numerical analysis with the Boundary Element Method (BEM) and Finite Element Method (FEM). Numerical analysis through meshless methods. Numerical analysis through hybrid Meshless/BEM numerical methods and FEM/BEM.

3.Software development
Development of ISoBEM ( www.isobem.com ), an advanced, user friendly BEM platform solving problems in the following fields: Potential problems, Acoustics
(sound propagation and radiation, scattering), Thermal problems, Electromagnetic problems (electric and magnetic field calculation, scattering by dielectric bodies and perfect conductors), Classical Elasticity (compressible and incompressible analysis, wave propagation and scattering, mechanical vibrations, fracture mechanics), Fluid-structure interaction, Strain gradient elasticity (microstructural effects), Computational fluid dynamics. ISoBEM performs 2D, Axisymmetric, 2.5D and 3D
analyses under static, harmonic and time domain conditions. The overall user experience is improved with an advanced and extremely powerful Graphical User
Interface for pre and post processing. Parametric modeling is also possible through a python shell available in ISoBEM that supports a wide variety of scripting commands.
ISoBEM is the main product of BEM S&S, a spin-off company ( www.bemsands.com ) created under the aegis of the Institute of Chemical Engineering and High
Temperature Processes.
