WELCOME

Dr. Ziad A. El-Sahn completed his undergraduate studies and received his B.Sc. in Electrical Engineering from Alexandria University, Egypt in 2002. From 2002 to 2005 he was working as a research and teaching assistant at Alexandria University. In 2005, he received his M.Sc. in Electrical Engineering from Alexandria University with a thesis entitled "Random Access Protocols for Future Optical CDMA Networks". Afterwards, Dr. El-Sahn joined the Centre d'Optique, Photonique et Laser (COPL) at Université Laval, Québec, Canada, where he received his Ph.D. in Electrical Engineering in 2010 with a thesis entitled "Smooth Upgrade of Existing FTTH Access Networks: SAC-OCDMA and Dense SS-WDM Solutions". From 2010 to 2012 Dr. El-Sahn was a postdoctoral research fellow at the Photonics Systems Group (PSG) at McGill University, Montreal, Canada. During that period, Dr. El-Sahn has worked on optical access networks, and coherent optical transmission systems.

Dr. El-Sahn is currently an Assistant Professor at the Electrical Engineering Department, Alexandria University. His main research is in optical communications, and he is currently teaching courses on Optical Communications, Optical Devices, Acoustics, Communication Systems, and Mobile and Wireless Communications.

Dr. El-Sahn is also the founder of the Photonics Group at Alexandria University, and he is a member at the SmartCI Center of Research Excellence at Alexandria University.
