Dr. Ephraim Chamiel earned his BA in economics and political science, and a diploma in business administration from the Hebrew University of Jerusalem. He worked in various executive positions for Bank Leumi, and in his fifties, returned to the university to study Jewish thought. He defended his dissertation in 2006 under the guidance of Professor S. Rosenberg and Dr. M. Silber (the present volume is a translation of the 2011 Hebrew publication of this study). His work explores the problem of combining the world of Torah and Jewish thought with the secular world, and considers this to be a matter of existential significance (one with which he struggles day in and day out).

Presently, he conducts research and teaches in the field of modern Jewish thought at the Hebrew University of Jerusalem. His second book Ladaat Torah - a modern reading of the Pentateuch - was published in 2013 in Israel (Hebrew).
