Representations

Details Date
National delegate to the new EU NanoSTAG action group on Nanomaterials. My appointment as national delegate to the COST Nanomaterials action is very important. This EU committee is highly influential in research programmes within the EU and gives me access to research data and information that is very useful for future planning within the Physics Department as well as my own research group. I also get the opportunity to meet with experts in Nanomaterials from other EU countries.
Member of the Irish Government Advisory panel to review and propose Irish priorities for the BRITE-EURAM III research programme on materials 1993-94. This panel briefed the Minister for Science and Technology on the strategy to maximise the participation rate for Irish Universities and companies within the BRITE-EURAM programme.
Member of the evaluation committee to review research proposals on Optical Functional Materials for the BRITE-EURAM and GROWTH programmes, May 1995, Oct. 1997, June 1999.
Member of the evaluation committee to review research proposals on Optoelectronics for the Forbairt Strategic Research Programme, April 1994, Optronics Ireland Advanced Technology Research Programme, July 2001. Confidential evaluation process of research proposals.
Local organizer for the annual conference of the British Medical Laser Association, September 1994, on "The use of lasers in the treatment of cancer".
Referee for journal articles in Physical Review Letters, Physics Review B (Condensed Matter), Journal of Luminescence, Electronics Letters, Optical Materials, Journal of Physics-Condensed Matter, Journal of Physics D, Semiconductor Science and Technology, Optics Communications.
Carried out consultancy work for IDA (Industrial Development Authority) Ireland on companies setting up facilities in Ireland to manufacture laser systems. Work was principally concerned with the feasibility of manufacturing such lasers and the market potential for them.
Served as thesis external examiner for Ms. Isabell Auffret, University of Wales, Cardiff, Nov. 1999, Mr. Dewei Jones, University of Wales, Bangor, May 2001. Mr. James Fryar, Dublin City University, Aug. 2001.
