Her research focuses on the early apocalyptic movements and literature and on the intellectual, cultural, and religious history of the early modern Iberian world, focusing on the history of the Portuguese Atlantic and the Iberian imperial ideologies. She is currently exploring the circulation of eschatological ideas within the space of the Atlantic and how Catholics, Jews, and Protestants engaged in an interreligious dialogue leading to expressions of religious tolerance while promoting the creation and development of intellectual networks. In addition, she analyzes the correspondence between eschatological networks and the so-called "religious terrorism" of the 21st century. She is the co-chair of the 'Bible and Empire' and 'Apocalyptic Literature' research programs at iSBL and co-chair of the "Apocalypse Now: Apocalyptic Reception and Impact Throughout History' seminar at SBL. She also organizes a yearly research program titled 'Violence in the Name of God' that created an international network of scholars with expertise in apocalyptic expectations, PoliSci, Peace Studies, and Terrorism. She has published widely on apocalyptic literature and imperial ideology in the Iberian world, particularly on the opus magnum of the Portuguese Jesuit António Vieira, the unfinished Clavis prophetarum. Her publications include "Historical Interpretations of the "Fifth Empire": The Dynamics of Periodization from Daniel to António Vieira, SJ" (Brill, 2011). She is the co-editor-in-chief of the peer-reviewed series 'Apocalyptic Trajectories' published by Peeters Publishers.
