Prof. John Donegan’s research interests are in Nanophotonics within two main areas. The first is quantum dot interactions; they are studying fluorescent quantum dot systems synthesised through colloidal processes. The other main study focus is microcavity interactions where they investigate mechanisms in coupled photonic micro-resonators which result in modified properties, such as directional emission, modification of the modal structure, and localised field confinement.
Prof. John Donegan received BSc and PhD degrees from University College Galway in 1982 and 1986. He had post-doctoral appointments in Lehigh University, Bethlehem, USA and in Max-Planck Institut für Festkörperforschung, Stuttgart, Germany. He was appointed to the academic staff in Trinity College Dublin in 1993, he is now a Fellow of Trinity College Dublin and Professor of Physics. He is a fellow of the Institute of Physics and the Institute of Nanotechnology, a senior member of the IEEE and the American Physical Society. He was recently the Head of School of Physics in TCD. Professor Donegan has collaborations with Ludwig-Maximilians-Universitaet Muenchen, University of Dresden, Université de Reims, and the Bell Laboratories, New Jersey. He has published 153 papers in journals and conference proceedings as noted in the web of science. He has made 15 patent applications.
