Established expertises in Optics, Lasers and their applications. Main activity is development of new lasers and laser customization, both compound semiconductor and fiber lasers, to address specific applications/needs. Present research focus on biomedical applications, cancer surgery and detection, innovative fibre laser in the infrared for healthcare, semiconductor devices, advance manufacturing using infrared lasers. He runs two main Laboratories: The Fiber lasers & Applications Laboratories and the Centre for Cosmetic & Curative applications of Compound Semiconductor Technology (C4ST). Laboratories are fully equipped to work in the whole spectral interval from 0.2 micron to 10 micron. A fully equipped Laboratory able to test optical communication components up to 50 Gb/s and above is also part of the resources. Collaborations include many Centres and companies, in particular the Compound Semiconductor Centre, Cardiff, UK.
