Area of specialisation: normative ethics & moral responsibility

My current project investigates collective action problems (e.g. donating and consuming). Why should one act in certain ways if one’s conduct makes no difference?

Solutions I’m working on are based on expected utility, complicity and universalizability.

Postdoc (2013-2016)
My postdoc project investigated the epistemic condition of moral responsibility, namely the extent to which responsibility depends on the information we have, and when we should gather more information. For example, does ignorance excuse for our so-called slavery footprint?


  • Externalism. Can the epistemic condition be analysed in terms of the available information rather than the perspective of the agent?
  • Moral concern. According to recent accounts, we are blameworthy when we don’t care enough – but what does this mean?
  • Strategic ignorance. What is strategic ignorance, and can strategically ignorant agents be held responsible, and in what sense?

PhD (2009-2013)
I wrote a PhD dissertation on infinite regress arguments. It investigated what such arguments from many distinct philosophical debates have in common, and provided guidelines for using and evaluating them.

In epistemology, I’ve also been interested in ancient skepticism. When and why should we suspend our judgment?
