About me

I am currently a senior research fellow at the Optoelectronics Research Centre (ORC), University of Southampton (United Kingdom). I was awarded my Laurea degree in Electronics Engineering at the Universit√† degli Studi di Pavia (Italy) and my PhD degree in Optoelectronics at the ORC with a thesis on “Holey optical fibres for high nonlinearity devices”. In the course of my career I have made several experiences both in the private and academic sector, always with the aim of developing technologies that may improve people health, relationship, safety or simply their comfort. My academic research activity in 3 top-ranked Universities in the optical fibre field as Lille, Bath and Southampton has concerned the development of Specialty Optical Fibres capable of providing the necessary tools to the medical and industrial sector for adopting the best possible light (the best colours/the best power) for treating diseases, or achieve mechanical perfection, or detecting environmental hazards, or also for fastening communications among people. But the most valuable experience for me has been having had the opportunity to step up into the  private sector and to work several years (2007-2012) as a research consultant in Lille (France) in the field of light/matter interaction. This experience, which also allowed me to be in charge of company based research programmes supported by the Agence National de Recherche (ANR) and by the European Commission, offered me the greatest stimulus in addressing in more concrete terms my knowledge in optics to practical applications.

It is in this great mixing of competences that resides the rarity of my profile and my best potential.
