From 2005 until 2008 he received a DFG Heisenberg Fellowship. Sven joined ICREA in 2008. From 2010 until 2013 he coordinated the FP7 ITN PETAF (EC-GA 238128), from 2010 until 2015 served on the executive committee of the Consolider-Ingenio PERSP (CSD2009-00056), and from 2016 until 2019 coordinated the H2020 ETN Diaphora (H2020-MSCA-ITN-2015-675415).

Sven's main research interests lie in metaphysics and epistemology. He is particularly interested in realism, objectivity, fallibility, the logic of justification, the limits of thought and knowledge (if any), and the philosophy of time and existence. Recently, Sven published a co-authored monograph on tensed theories of time with Springer. His latest book, Justification as Ignorance, concerns the nature and logic of epistemic justification and was recently published by Oxford University Press.
