Honorata Mazepus is an assistant professor at the Institute of Security and Global Affairs. She is also working as a post-doctoral researcher on the EU-STRAT project focusing on socio-political processes in the Eastern Partnership countries. Extension number: 6752.

In her PhD dissertation, What makes authorities legitimate in the eyes of citizens? An investigation of perceived legitimacy in different political regimes, Honorata investigated how people reason about legitimacy. She also tested the effects of outcomes and fairness on perceived legitimacy of governments across political regimes (France, Netherlands, Poland, Ukraine, and Russia).

In 2018, she received an academic talent support grant from Leiden University Fund and Gratama Stichting to study experimentally the role of moral principles in legitimizing international interventions.
