The general area of my research is the organization and transmission of knowledge in early modern Europe. This involves the history of interpretation in the higher faculties (law, medicine, theology) and the economics and modalities of the trade in learned books in the period. I have completed a third volume on this last topic which is due to appear in 2020 entitled 'Episodes in the life of the early modern learned book'. I have also completed a study of the reception of Hippocrates in late seventeenth-century Europe, which is due to appear in a volume co-edited by Dmitri Levitin and myself entitled 'Classical reception in early modern Europe: comparative perspectives'. My present project is a study of the last writings of Girolamo Cardano, which will include a partial edition of his final work, the 'De prudentia eximia'.
