Research

My research focuses on political psychology, particularly how conspiracy theory beliefs relate to political attitudes and trust. I examine these relationships across social media environments and national contexts, including their connections to attitudes toward foreign countries and immigrants.

I also study political leaders’ beliefs and foreign policy preferences through operational code analysis, with a focus on Turkish foreign policy.
