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 a practical and industrially focused approach, especially in the field of optical fibre technology.

Lourdes has a good publication record for an early-career researcher of both peer reviewed journal and major international conference publications. Since joining Edinburgh Napier in 2013, she has been actively seeking for opportunities to continue her research career within the highly topical and promising field of optical fibre sensors.
