Biography

Elfed Lewis was born in Holyhead, Wales in 1959. He graduated with BEng (Hons) in Electrical and Electronic Engineering from Liverpool University in 1981. He was awarded a PhD from University of Liverpool in 1987 for work on high speed photography and spectroscopy of electric circuit breaker arcs during the current zero phase.Following this, he worked as development engineer with BICC Telecom. Cables, Prescot, Merseyside in conjunction with University if Liverpool developing chromatic modulation based optical fibre sensors for a wide range of applications. In 1989 he Joined Liverpool John Moores University where he initiated the research activity in Optical Fibre Sensors. The group investigated sensors for environmental monitoring including water contamination and pH.In 1996 he joined University of Limerick at which time he established and has since led the Optical Fibre Sensors Research Centre. He is Associate Professor and Director of the Optical Fibre Sensors Research Centre at University of Limerick. He is Fellow of Institute of Physics, IET and Senior member IEEE. He has authored and co authored more than 140 journal papers and made in excess of 300 contributions to international conferences. He currently holds 9 patents on Optical Fibre Sensor Devices. In 2005 he was recipient of the University of Limerick Special Achievement in Research Award and was a Fulbright Scholar with CREOL (University of Central Florida) in 2008. He was Distinguished Lecturer for IEEE Sensors Council for the period July 2013-June 2015 and is currently Vice President for Technical Operations for IEEE sensors Council. HE was General Chair of the IEEE Sensors 2011 conference and European Workshop on Optical Fibre Sensors (EWOFS 2016) held at University of Limerick. He will be co-chair of the forthcoming IEEE World Forum on Internet of Things (WFIoT) (April, 2019).
