My classes are linked with my research interests. The introductory course I teach explores the impact of the city on human life from the Neolithic period to the seventeenth century, while my advanced courses focus on the European Middle Ages, particularly the religious, intellectual, and legal developments of that era. Medieval conflicts over religion and politics, and the medieval revival and reinterpretation of classical governmental notions, had surprising and profound consequences for later European, American, and even global society. The last course I have developed, “Representation, Rights, and Democracy, 1050-1792,” treats one of these developments: the evolution of the unique conceptions of government and the citizen-subject that we now closely identify with modernity. My recent research explores the pivotal shifts in European political thought that emerged during the bitter conflicts among ecclesiastical leaders, secular authorities, and religious dissidents in the fourteenth century. The articles I have published so far have centered on lesser-known controversialists of the period; a book-length project will examine the full impact of their debates.
