PhD in Theoretical Philosophy.

Research Focus

I am working primarily in social epistemology, with a particular focus on conspiracy theories, rationality, expertise, trust, and misinformation.
I received my PhD in Theoretical Philosophy from Lund University in 2025 with the dissertation Dimensions of Conspiracy: An inquiry into the cognitive and epistemic standing of conspiracy theories.
I am currently a Lecturer in Philosophy at Macquarie University,
where I contribute to Mark Alfano’s ARC Future Fellowship project on trust and knowledge formation in social and epistemic networks.
I also co-lead the Pufendorf Institute project Anomalous Agenda with Prof. Anders Warell, and am a member of the CogPhi research group.
Alongside my research, I am active in public philosophy:
I co-host Filosofiska Podden med Mogensen och Tsapos 
with radio journalist Lars Mogensen
and host the YouTube channel In-Depth Conversations.


I recently completed my doctoral thesis,

Dimensions of Conspiracy
– an inquiry into the cognitive and epistemic standing of conspiracy theories
,

which develops a new framework for understanding the cognitive and epistemic standing of conspiracy theories.
