I study a wide range of problems in Italian and Italian American History, and European history in general, with particular concentrations in medieval and Renaissance intellectual history, humanism, social history and statebuilding. In recent years I have been working on projects concerning interactions between 16th century Florence and northern Europe, Renaissance historical writing, Niccolò Machiavelli's political thought, early interactions between Italy and America, and prosecutions for blasphemy in early modern Europe.
