A. Tunç Şen is a historian of the Ottoman Empire and its many connections with the early modern world. His past and future publications focus on the history of sciences and divination, manuscript culture, the history of emotions, and the social history of scholarship. His forthcoming first book, based on his award-winning dissertation and tentatively titled Forgotten Experts: Astrologers, Sciences, and the Empire of the Ottomans in the Long Sixteenth Century, examines what "scientific authority" and "expertise" meant in the early modern context. Besides his service as the Deputy Director of the Sakıp Sabancı Center for Turkish Studies at Columbia University, Şen is a member of an international research project, Geographies, and Histories of the Ottoman Supernatural Tradition (GHOST): Exploring Magic, the Marvelous, and the Strange in Ottoman Mentalities, funded by the European Research Council.
