Dr. Victor Weiss (business advisor)

Victor Weiss received his B.Sc., M.Sc. (with distinction), and his Ph.D. degrees in Chemistry and Applied Physics from the Hebrew University of Jerusalem,  and from The Weizmann Institute of Science Rehovot,  Israel, where he also was a Fellow Scientist. His main fields of research and technology development (RTD) include electrooptic materials, devices, and systems, in which he has published and presented over 45 scientific (peer-reviewed) papers, and is an inventor in seven groups of patents/applications. He worked for Ilford – Ciba-Geigy (Novartis) in Switzerland, and between 1994-2012 at Elbit-Electrooptics Industries (ELOP) in Israel as an RTD program manager of EU and Israeli funded consortia, and was heading the center of excellence for Advanced Planar Optronics & Display Technologies. Victor also initiated an RTD program on Nano-Optronics for advancing and improving product development, funded by the Chief Scientist of the Israeli Ministry of Economics. His merits to lead and advance innovating technologies and projects were recognized at ELOP by promoting him to the degrees of Senior Scientific Expert and to Scientist in 1998 and 2001, respectively. 

Dr. Weiss served as Deputy Chief Scientist of the Israeli Ministry of Science, Technology& Space (MOST) 2012-2015. He also served as a representative of MOST in local and European (EC) technical steering committees. In 2014, he served as co-chair of ICIS2014, the International Congress of Imaging Science, which he has brought for the 1st time to Israel. In this context, he also was a guest editor of the peer-reviewed proceedings in JIST.

Since 2015, Dr. Weiss serves as a delegate in Israel for the Organization of Swiss Abroad (ASO) vis-à-vis Swiss administration and politics. Since 2015, he is involved in the philanthropic activity as the project manager and director on the board of the Swiss Village of Kiryat Yearim near Jerusalem. Victor is highly proficient in several languages, such as English, German (and Swiss German), French and Hebrew, orally and written, and Italian and Yiddish (simple conversation).
