Silvianne Aspray (née Bürki)


Silvianne Bürki is a doctoral candidate in Philosophical Theology at the Divinity Faculty in Cambridge. Her research focuses on the metaphysics of the 16th century Reformation by means of a case study of Peter Martyr Vermigli (1499-1562). In particular, she traces the metamorphoses of a participatory ontology in Vermigli's work, and delineates where its participatory, mediatory and realist elements stand in tension with more univocalist and non-mediatory aspects in his thought. More broadly, her work will contribute to a hermeneutics of the Reformation as an epoch, by addressing how ‘modern’ it was, and what it gave rise to that was – metaphysically speaking – ‘new’. 

Silvianne is being supervised by Prof. Catherine Pickstock and advised by Prof. Alexandra Walsham. She holds a Cambridge International Trust doctoral scholarship. During Michaelmas term 2015 she conducted research at the École Normale Supérieure in Paris, where she had been awarded an exchange studentship.

Being a Swiss native, Silvianne took a BA and MA in Theology from Bern University (Faculty prize), and studied for a year in Durham. Before moving to Cambridge in 2013, she was a research assistant both to the Praeses of the Swiss Protestant Churches and to Prof. Peter Opitz (University of Zurich).
