Faculty & staff

Lecturer at Holon Institute Technology, Israel.

In 2000 he finished his M.A on the subject of optical coherent multiplexing CDMA. Between 2000-2003 Gilad worked as electrical engineering in the free space optics field, developing a sophisticated laser transmitter and optical receivers. In his Ph.D. degree between 2003- 2006, he has investigated electrical digital signal processing (DSP) techniques to mitigate intersymbol interference (ISI) effect in optical communication systems. This research led to a startup company in 2006 – 2018 which was a leading company that developed the next generation ICs at 100Gbps and 400Gbps for fiber optic networks.

He has published more than 20 papers on subjects as DSP for optical communication systems, DSP for free space optics, DSP for analog circuits and more.
