Profile Summary

John T. Sheridan was born in Castlebar, Co. Mayo, Ireland, where he attended St Patricks National School and St Geralds College. He received his Bachelors degree (H1) in Electronic Engineering, from University College Galway (NUIG) in 1985, and his Masters degree in the Science of Electrical Engineering, from Georgia Tech, in 1986. While at GT he worked as a Research Assistant of Prof. William T. Rhodes. In 1987 he matriculated as a member of Jesus College Oxford and in 1991 he was awarded his doctorate by Oxford University for work carried out under the supervision of Prof. Laszlo Solymar and Prof. Colin J. R. Sheppard.

This was followed by postdoctoral research fellowships, supported first (1991) by the Alexander von Humboldt Foundation and later (1992) by a European Community Bursary. Both were held at the Lehrstuhl fur Angewandte Optik in Erlangen-Nürnberg University, under the leadership of Prof. Dr A. W. Lohmann. In 1994 he took up a position as a visiting scientist at the European Commission Joint Research Centre, in Italy. In 1997 he was appointed to the School of Physics, Dublin Institute of Technology as a permanent lecturer.

He joined the Dept. of Electronic and Electrical, Engineering, University College Dublin (UCD), in 2000 as a College Lecturer. In 2005 he became a Senior Lecturer, and in 2007 Professor of Optical Engineering within the UCD School of Electrical, Electronic and Mechanical Engineering. He currently acts as Deputy Director of the UCD Communications and Optoelectronic Research Centre and of the SFI Strategic Research Cluster in Solar Energy Conversion.

He has authored ~350 papers, regularly serves on international conference committees and is a member of the editorial boards of several peer reviewed journals.

John is married to the very wonderful Dr Jutta Baum-Sheridan and is the extremely proud father of M. Daniel O. Sheridan.
