Following a post-doctoral fellowship at the University of Chicago, in 2005 he moved to Israel, where he joined the faculty of the Hebrew University of Jerusalem, initially as a Mandel Post-doctoral Fellow at Scholion – Interdisciplinary Center for Jewish Studies, and subsequently (since 2006) as a full-time lecturer at the Department of Jewish Thought. Dr Maciejko has published extensively in leading academic periodicals on Jewish studies and has held a number of visiting positions at academic institutions worldwide, including University of Pennsylvania, École des hautes études en sciences sociales in Paris, the Simon Dubnow Institute in Leipzig, and the Jagiellonian University of Kraków. He has received grants and fellowships from the Rawnsley Fund, Spalding Trust, the Österreichischer Austauschdienst, the DAAD, the Whiting Foundation, YIVO Institute, the Vigevani Trust, and the Israel Science Foundation, among others. In 2010, he was awarded a Starting Grant of over one million Euros from the European Research Council for a project on the theological conceptualisations of Jewish conversions to Christianity in the early modern period. His book The Mixed Multitude: Jacob Frank and the Frankist Movement 1755-1816 has been published by University of Pennsylvania Press. The book won the Salo Baron Prize awarded the American Academy of Jewish Research and the Polonsky Prize for Creativity and Originality in Humanistic Disciplines from the Hebrew University.
