Giorgio Pini's area of specialization is medieval philosophy. His research focuses on the metaphysics, theories of cognition, and philosophical theology of John Duns Scotus and other later medieval thinkers, such as Thomas Aquinas, Henry of Ghent, and Giles of Rome. He is particularly interested in tracing the consequences of theological debates on philosophical issues.
In the last few years, he has been working on the critical edition of an hitherto unedited commentary on Aristotle's Metaphysics by Duns Scotus (called Notabilia super Metaphysicam), which he discovered some years ago; the edition is now basically done. His next projects are on (1) the role and demise of intelligible species between the thirteenth and the fourteenth century; (2) a number of assorted metaphysical issues, including the concept of univocity and analogy in Duns Scotus and several other thinkers.
