At the beginning of the 1980’s my centers of interest were mainly Medieval studies, particularly Hebrew grammar and booklore. In the following years my work expanded, focusing especially on Jewish symbols and Kabbalah, of which I analyzed historical development,
literary values and aesthetic implications.
I dedicated quite a number of studies to the history of the relationship between Jewish and Christian culture in Italy during the Middle Ages and the Renaissance.
I am the general editor of a series that aims to publish
the entire kabbalistic library of the humanist Giovanni Pico della Mirandola.
