Professor John Donegan

Professor (Physics)

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 arrived back in Ireland in 1990 taking an appointment with the newly created Optronics Ireland research centre under the supervision of John Hegarty. He was appointed to the academic staff in Trinity College Dublin in 1993, he is now a Fellow of Trinity College Dublin and Professor in the School of Physics. He is a fellow of the Institute of Physics, a senior member of the IEEE and the American Physical Society and the Optical Society of America. He was the Head of School of Physics in TCD from 2008-2011. His research is in Photonics, the Science and Technology of the creation, detection and use of light. Professor Donegan has had collaborations with Ludwig-Maximilians-Universitaet Muenchen, and Université de Reims, Presently, he has collaborations with University of Erlangen-Nurenburg, Huazhong University of Science and Technology, Wuhan and with industrial laboratories in Nokia-Bell Labs, and Western Digital Corporation. He has published over 350 papers in journals and conference proceedings with over 8000 citations and a h-index of 38. He has 8 granted patents.
