Dan Sadot

Sadot was born in Maracaibo, Venezuela, and immigrated to Israel in 1967. He served in the Israeli Air Force from 1981 to 1984.^[3]

He received B.Sc., M.Sc., and Ph.D. degrees in electrical and computer engineering from Ben‑Gurion University. Sadot won the Clore doctoral scholarship and completed his doctorate summa cum laude in 1994 on electro-optical remote sensing under the supervision of Natan Kopeika.^[4][5]

Sadot was a Fulbright and Rothschild postdoctoral fellow in optical communications at Stanford University, supervised by Prof. L. G. Kazovsky.^[6][7] He then joined the Electrical and Computer Engineering (ECE) Department at Ben‑Gurion University as a senior lecturer in 1995, becoming an associate professor in 2001 and a full professor in 2009.^[4]

Sadot served as the ECE department chair (2007–2013) and vice‑dean of the Faculty of Engineering (2006–2008). In 2001, he was appointed to the Reuben and Frances Feinberg Chair in Electro‑Optics at Ben‑Gurion.^[8][1]

Over the years, Sadot held visiting academic positions at other universities and research institutes, including Bell Labs in New Jersey.^[3]

Sadot has supervised 14 Ph.D. students and more than 40 M.Sc. students. He has authored over 230 scientific publications in journals and conferences and holds 35 patents.^[9][10]

Sadot’s research focuses on optical communication and networking.^[11]

His studies include signal processing in optical communications, coherent detection, optical OFDM, atmospheric optics, dynamic WDM networks, and security in optical communication networks.^[10][12]

Sadot has founded several start‑ups: TeraCross (1999–2002), Xlight Photonics (2000–2003), MultiPhy (2006–2018), and Banias Labs (2020–2022), which was acquired for $240 million by Alphawave.^[13][2]

In 2022, Sadot founded CyberRidge, a company that protects data traveling over fiber‑optic networks by encrypting it at the photonic (light) layer. He also serves as its CEO.^[10]
