He has an MSc. in Mechanical Engineering from IST (1985), a Ph.D in Mechanical Vibrations from Imperial College London (1989) and Habilitation from IST (2001). He has authored around 230 publications, including two textbooks. He has organized 10 international conferences on Structural Dynamics, supervised 10 Ph.D students and coordinated national and international research projects. Dario Di Maio is Associate Professor of Mechanical Engineering at the Engineering Technology Faculty of University of Twente, The Netherlands. He has an MSc. In Mechanical Engineering from University Politecnica delle Marche, Italy (2001), a Ph.D. in Mechanical Vibrations from Imperial College London (2007). He had a long collaboration with Rolls-Royce plc. through the Vibration and Composite University Technology Centre at Imperial College London and University of Bristol in the research areas of structural dynamics and composite fatigue failure. He authored around 100 publications. He was a leading figure of the Society of Experimental Mechanics (SEM) in the International Modal Analysis Conference (IMAC). He supervised 10 PhD students and more than 50 MSc. Students. Alessandro ‘Alex’ Carrella has a degree in Aerospace Engineering from the University of Naples (Italy) and was awarded a PhD in Structural Dynamics at the ISVR (University of Southampton, UK). He was a lecturer in Structural Dynamic at the Dept of Aerospace Engineering at the University of Bristol when he left academia to join LMS (now Siemens) as Product Manager for Dynamic Environmental Test solutions first and then as manager of Aerospace&Defense Business development. Today he runs his own vibration and acoustic consultancy firm as well as directing the international operations at MSI-DFAT. Alex is an active member of the international space testing community and serves on technical and managing boards of major conferences.
