Dr Lourdes Alwis

Lecturer

Biography

Following a first class (Hons) degree in Electrical, Electronic and Information Engineering from City University London (2005), Lourdes was offered a scholarship to commence a part-time PhD at the same establishment. She completed her thesis on the optimisation of polymer coated long period grating-based sensors for structural health monitoring applications, in 2013.

Lourdes has significant industrial experience, having worked within the R&D section of Alcatel-Lucent Ltd. for over 7 years, a company specialising in design, implementation, build and test of optical fibre telecommunications products. The work at Alcatel-Lucent has given her valuable industrial experience through which she gained both practical and industry focused approach, especially in the field of optical fibre technology.

Since joining Edinburgh Napier in 2013, she has been actively conducting her research career within the highly topical field of optical fibre sensors. She had been working on a range of projects from civil engineering to biomedical engineering applications where state-of-the-art sensors are utilised.
