A graduate of the Physics Department, UCC (BSc), and Department of Physics, Trinity College (PhD), his PhD thesis (2004) focused on analysis of the pulsed laser deposition and growth of III-nitride thin films for photonic applications. Post-doctoral visiting researcher (Willhem-Simon fellowship) with the Materials Group at Paul Scherrer Institut, ETH Zurich (2005) and Post-Doctoral researcher with the III-V Materials & Devices group (Brian Corbett) at the Tyndall National Institute (2005-2008). Staff researcher at the Tyndall National Institute 2008-2015 and lecturer at CIT Department of Physical Sciences, 2015-2016 (Acting Head of Department, 2017-present). Having also worked as technical/project lead on various national and international projects funded by, Enterprise Ireland, Science Foundation Ireland, EU H2020, European Space Agency. Past/Present research interests include: growth and processing of III-V materials for photonic applications (n.b LED, PV), evaluation of wide bandgap semiconductor materials and devices for harsh environments (e.g. Space), photonic sensors/instrumentation for environmental and process monitoring, development of solar PV technology qualification facilities in Ireland.
