Personal profile

Biography

Currently Reader at Heriot-Watt University, School of Engineering and Physical Sciences. Dr Shephard’s research (Applied Optics and Photonics) is targeted at number of areas: Developing novel optical fibres for high power laser delivery; Technologies for integrating lasers into manufacturing processes; Adaptive optics to tailor light to specific applications; Optical non-destructive testing, and; Novel laser processes for medicine. There is an emphasis on developing multidisciplinary links with academic and industrial partners and medical end users such as surgeons and dentists.

 

Dr Shephard received the BA degree in Engineering at St Johns College, Cambridge University in 1994 and then joined Pilkington Plc (1994-1995) working within R&D. He then returned to study within the Department of Engineering Materials, University of Sheffield and was awarded an MSc (Eng) with Distinction in 1996. He subsequently remained at the University of Sheffield where he worked on developing novel mid-IR transmitting optical fibres and waveguides. He obtained his PhD in 2000 for his work on “Surface modification of IR transmitting glasses for integrated optics” and continued to work in the area of novel mid-infrared fibres and optical materials. In 2003 he joined the Applied Optics and Photonics Group at Heriot-Watt University, working on the development of novel micro-structured (Photonic Crystal) fibres, and is now a Reader within the Institute of Photonics and Quantum Sciences.
