Research themes

Eoin O’Reilly’s research seeks to improve the fundamental understanding of photonic materials and devices, to enable the design of structures for new capabilities and applications. The programme is built upon fundamental investigations of the electronic structure and light-matter interactions in optoelectronic materials and devices. These include studies of carrier-carrier interactions and gain and loss processes in such systems, as well as investigations to optimise specific novel devices, providing considerable synergy with the experimental photonics expertise in Tyndall National Institute.


Eoin O’Reilly was born in Dublin, Ireland, received the BA (MOD) degree in Theoretical Physics from Trinity College, Dublin, and obtained a PhD in Theoretical Condensed Matter Physics at the University of Cambridge.


Eoin was appointed as a lecturer at the University of Surrey in 1984, where he was head of the Department of Physics from 1997 to 2001. He is Chairman of the Board of the EPS Condensed Matter Division. He was Scientific Chairman of the combined CMMP-EPS CMD meeting in Brighton in April 2002, when the annual IoP Condensed Matter and Materials Physics conference was held in parallel with the 19th General Conference of the European Physical Society Condensed Matter Division, and has since been joint Chair of three further EPS Condensed Matter conferences held in Dresden, Rome and Warsaw.

O’Reilly’s list of over 250 publications includes seven book chapters, several major review papers, articles for Physics World, and papers on undergraduate laboratory experiments. His MPhys-level text on the “Quantum Theory of Solids” was published by Taylor & Francis in 2002. He is a Fellow of the Institute of Physics (FInstP) and of the Institution of Engineering and Technology (FIET). He is a member of the editorial Board of Semiconductor Science and Technology.
