Nadia Beider is a doctoral student in the department of Jewish History and Contemporary Jewry at the Hebrew University and a member of the “Setting Tables” research group at the Mandel Scholion Research Center. Her dissertation, under the supervision of Professor Uzi Rebhun examines religious conversion based on the Pew Religious Landscape Study in America and the Pew study of religion in Israel. She takes a quantitative approach in order to assess the determinants of different forms of conversion, as well as to establish the effect of conversion on social network composition and religiosity, revisiting the question of the zeal of the convert.  Religious identity in the twenty-first century is unstable and fluid, leading to the creation of new, hybrid forms of religious engagement, with converts acting as agents of cultural transfer.
