After graduating from the Real high-school in Haifa, and following a mandato- ry military service, he completed the bachelor, masters and doctorate degrees in elec- trical engineering at the Technion in 1997 and joined the light-wave research lab of AT&T in Red Bank NJ. His initial position at AT&T was ofa post-doctoral fellow, but he was soon promoted to the position of a senior and subsequently principal member of technical staff and specialized on the theoretical modeling of fiber communications systems. In 2000 he assumed the position of a principal architect at a newly established optical communication start-up named Celion Networks. Later in 2002 he joined Tel Aviv University's faculty of engineering, where he has been teaching and conducting research ever since. His fields of research focus primarily on fiber optics and optical communication systems. Within this general area of activity he integrates the fields of optics, quantum theory, nonlinear systems, communications theory, information theory, and signal processing. Over the years he has contributed to a variety ofto- pics including optical amplification, analysis of nonlinear propagation, polarization- related phenomena, analyses of noise and signal detection, quantum information in fiber systems, and fundamental limits to optical communications. In the years 2014 - 2017 he headed the department of Physical Electronics within the School ofElectrical Engineering in Tel Aviv University, and ni he was the head of the entire school.
