Sonja Kmec is working on women鈥檚 history and gender studies, currently on the project 鈥淢usic and Gender in Luxembourg鈥 (). She is also active in memory studies. She has studied usages of the past (Lieux de m茅moire au Luxembourg; Inventing Luxembourg; D茅passer le cadre national des lieux de m茅moire) and focused then on material aspects of remembering: monuments and cemeteries as well as rituals. This research led her to examine the impact of migration and cultural and religious pluralization on memory cultures (cemi-hera.org). Another strand of her research are international relations and small nations, using Luxembourg as a case-study. Sonja is a member of the editorial board of the 鈥淩evue d鈥檋istoire luxembourgeoise H茅mecht鈥 () and 鈥淔orum f眉r Politik, Gesellschaft und Kultur鈥 ().
