My main research activity is devoted to developing improved understanding of integrity and reliability of engineered and natural structures and systems, from high-performance metallic alloys to polycrystalline ceramics to natural hard tissue, such as human dental enamel. My expertise concerns structure and properties across the scales, and the advanced methods of materials characterisation and modelling. I have been one of the major contributor to the development of advanced method for local advanced approaches for the fatigue of fracture assessment of materials weakened by defects and geometrical discontinuities. I have devised several novel engineering methods suitable for designing notched, cracked and welded components against static, dynamic and fatigue loading. The work done in the above research areas has led to about 400 scientific papers in the period 2004-2016. My research has attracted significant interest from the international scientific community, this being proven by a Google Scholar H-index of 41 with ≈5.0k citations in total. 

As stated above since 2003, I have been working on different aspects of the structural integrity discipline, by mainly focusing attention on problems related to the static and fatigue assessment of engineering materials and components. In particular, I have attempted to devise engineering methods suitable for designing components (experiencing different kinds of stress concentration phenomena) against fatigue as well as against static failures at all scale levels.
My areas of expertise can be briefly summarised as follows: fracture and notch mechanics, asymptotic methods, local approaches for advanced design in presence of complex loadings and fracture and fatigue behaviour of advanced innovative materials at all scale levels.
