John T. Sheridan was born in Castlebar, Co. Mayo, Ireland, where he attended St Patrick's National School and St Gerald's 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, (MScEE), 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 in the Department of Engineering Science. 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 Department 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 and Electronic Engineering. He has acted as Deputy Director of the UCD Communications/Optoelectronic Research Centre and also of the SFI Strategic Research Cluster in Solar Energy Conversion. He became a Fellow of SPIE the International Optical Engineering Society in 2014 (FSPIE), a Fellow of the Optical Society of America (OSA) in 2016, and in 2018 a fellow of the Institute of Mathematics and its Applications, (FIMA). He has authored ~600 documents (>225 in peer reviewed journals), which have been widely cited (ISI Web of Science: >5800 citation, h-index ~40. Google Scholar: >8500 citations, h~48). See: He has supervised >21 PhDs to completion. He regularly chairs and serves on national and international conference committees and review panels, (See: ) and is a member of the editorial boards of several international journals. He is a co-founder and director of the UCD startup company Equilume, (See and ). He is the co-editor of "Linear Canonical Transforms: Theory and Application," Springer Series in Optical Sciences (2016). and co-authored the monograph "Optical Encryption and Decryption", SPIE Press (2019). He acted as lead editor of the 2018 Applied Optics Feature Issue: "Optics in Ireland". He is actively engaged in collaborative projects with national and international academic and industrial partners. He presented the following public lecture at the UCD Light & Shadow event.
