Her work on Renaissance humanism and on Platonism, Aristotelianism, Stoicism, Epicureanism, and scepticism in Renaissance philosophy has appeared in many contributions to scholarly journals and academic books and has been translated into Italian, French, German, Spanish, Portuguese, and Polish.
A collection of her essays was published in 2002 as Classical Traditions in Renaissance Philosophy.
Professor Kraye was associate editor of The Cambridge History of Renaissance Philosophy (1988) and edited the Cambridge Companion to Renaissance Humanism (1996) and Cambridge Translations of Renaissance Philosophical Texts (2 vols, 1997).
The range of her interests is reflected in the volumes she has jointly edited, which include Caro Vitto: Essays in Memory of Vittore Branca (2007), Conflicting Duties: Science, Medicine and Religion in Rome, 1550–1750 (2009), Vernacular Aristotelianism in Italy from the Fourteenth to the Seventeenth Century (2016), The Afterlife of Aldus (2018) and The Marriage of Philology and Scepticism (2019).
She has been a co-investigator on a number of research projects funded by the AHRC and the Leverhulme Foundation.
In 2018 a group of her students and friends published Et amicorum: Essays on Renaissance Humanism and Philosophy in Honour of Jill Kraye.
Bill Sherman, director of the Warburg Institute, commented:
Jill Kraye is a consummate scholar-librarian in the finest Warburgian tradition. She has served the Institute, its students, its readers, and her fellow scholars of Renaissance humanism with work of the highest standard since the early 1970s. We are delighted to see her honoured by the British Academy.
