I particularly focused on the history of culture, mentality, and society. The investigation until now involved, for the high Middle Ages, the conception and treatment of sin through the study of penitential books (up to that of Burcardo).
For the low Middle Ages, items revolve around preaching and its effects. Among the effects are the Montes Pietatis and the modification of the relationship with the Jews. The theme of the Montes Pietatis and its ethical-economic conception is a constant interest of Maria Giuseppina Muzzarelli.
Since many years, I studied the fashion phenomenon in his medieval origins, and in particular, the sumptuary laws, useful also for the reconstruction of the history of consumption as well as the history of customs. The study of veils in the West is also part of this last interest.
Female figures and roles have in recent years been a recurring research topic: from Gracia Mendes to Christine de Pizan. In particular, I studies the relationship between women and food: food to nourish, to regulate relations, but also to weaken and kill.
