Iryna Klymenko (PhD in History 2018, Ludwig Maximilian University of Munich) is a postdoctoral researcher at Ludwig Maximilian University of Munich. She publishes on discursive semantics of social transformation in early modern Europe, synergies between historiographies of Western and Eastern Europe, and historical theory and method.

Her POLY fellowship in the Winter Term 2020/21 focused on two closely-related book projects. The first investigates the cultural histories of abstinence and fasting in the ethnically diverse and multi-confessional cities of the Polish-Lithuanian Commonwealth (1540–1648); the second studies early modern Jewish body practices and administrative self-regulation in multi-confessional Polish-Lithuanian cities.

In the Winter Term 2025/26, she returned to POLY as a Writing Fellow in the Writing Group "(Re-) Ordering Time." During the group's meetings at Forschungskolleg Humanwissenschaften Bad Homburg in January and June 2026, she developed her contribution to the first volume of POLY's forthcoming three-volume book project, Doing Christianity: A Praxeological Guide to Polycentricity and Plurality of Premodern Christianities.
