Biography

John J. Healy was born in Co. Dublin, Ireland in 1983. He was awarded the B.E. and Ph.D. degrees in Electronic Engineering from University College Dublin in 2005 and 2010. He has worked as a postdoctoral fellow in Physics in UNAM, Mexico, and in Computer Science and Electronic Engineering in Maynooth University. In 2012, he was awarded the NUI Postdoctoral Fellowship in the Sciences. He has been a Lecturer in Electrical, Electronic and Communications Engineering in UCD since 2015. He is a member of the IEEE, the OSA and the SPIE.
