Before joining the JDP, Rosen attended numerous traditional and innovative yeshivot in Israel. His research focuses both on the history of Midrash and Medieval Kabbalah. He hopes to write his dissertation on poetic and politico-theological aspects of Zoharic literature as situated within a history of late Midrash and Christian hermeneutical and political figurations. At Berkeley, he has taught courses in advanced Talmud, and he is involved in local Jewish adult education.
