<b>Professor Salah Obayya, University of Glamorgan, UK</b><br />Salah Obayya received a BSc in Electronics and Communications Engineering from Mansoura University, Egypt in 1991. Between Oct 1991 and Sept 1996 he worked as an Engineer with the Telecommunications Authority, Egypt. In September 1996, Obayya joined the Department of Electrical, Electronic and Information Engineering, City University London to study for his PhD, in which he developed a novel finite element based full vectorial beam propagation algorithm for the analysis of various photonic devices. Following his PhD, and from Jan 2000 to June 2003, Obayya worked as a Senior Research Fellow at the School of Engineering, City University London. In June 2003, he joined the School of Engineering and Design, Brunel University, UK as a Lecturer, and subsequently became a Senior Lecturer in Oct. 2005. In Sept. 2006 Obayya joined Swansea University as a Reader and moved on to the University of Leeds in July 2007. Obayya is currently Full Professor and Chair in Photonics at the University of Glamorgan where he leads the "Photonics Research Group".
