Personal website

I hold a PhD from Humboldt University Berlin (2012), a BPhil from the University of Oxford (2010), and an MLitt from the University of St Andrews (2008), all in Philosophy. As an undergraduate, I studied Political Science, Philosophy, and Religious Studies at Ludwig-Maximilians-University Munich (LMU) and at the Hebrew University of Jerusalem.

My main areas of interest are in metaphysics, philosophy of mathematics, and epistemology. My monograph Ineffability and its Metaphysics: The Unspeakable in Art, Religion, and Philosophy has been published in 2016 with Palgrave Macmillan, offering the first systematic account of the concept of ineffability.

Besides questions about the limits of expression, most of my current work focuses on shared metaphysical and epistemic problems for a priori domains such as mathematics, ethics, modality, and religion.
