I teach Christian Spirituality at Tilburg University, School of Catholic Theology, Franciscan Study Center. I hold a Ph.D. (2007) in Medieval History from Radboud University Nijmegen and a Ph.D. and S.T.D. (2019) in Medieval Theology from KU Leuven. I published three books, four volumes, and multiple translations in Dutch. My English publications include Franciscan Virtue: Spiritual Growth and the Virtues in Franciscan Literature and Instruction of the Thirteenth Century (Leiden/Boston: 2012) and the edited volumes The Carthusians in the Low Countries: Studies in Monastic History and Heritage (Louvain: 2014), (w. A. Plunkett-Latimer) Shaping Stability: The Normation and Formation of Religious Life in the Middle Ages (Turnhout: 2016), and A Companion to Medieval Rules and Customaries (Leiden/Boston: 2020). I am Chairman of IGTM - International Society for the Study of Medieval Theology (www.medievaltheology.org) and Chief Editor of Franciscan Connections (www.franciscanconnections.com).
My research concerns virtue and environmental ethics, character building, Christian moral and spiritual traditions, Franciscan history and spirituality, and religious orders and religious life.
My current research projects are Character Building in the Theological Curriculum, Virtual Virtuosity: Building Character Through Practical Wisdom in a Digital World, and Transitus: A Theology of Discontinuity, Death, and Completion.
