I specialize in medieval and renaissance philosophy and the history and philosophy of logic.
My recent focus has been on late medieval theories of metalinguistic discourse – when linguistic signs "turn on themselves," as in cases of quotation or mention. Medieval logicians call this material supposition (suppositio materialis).
My dissertation, supervised by Brian Copenhaver and Calvin Normore, traces the development of material supposition theory over the course of the fourteenth century, with emphasis on the views of William of Ockham (ca. 1287 – 1347), John Buridan (ca. 1300 – 1362), and Paul of Venice (1368/9 – 1429).
