His project investigates the phenomena of Tibetan Buddhist paratexts from historical, philological, and empirical perspectives, focusing on the Tibetan texts in the Chester Beatty collection. Some of the key research questions are what the nature and function of paratexts in the Tibetan Buddhist textual tradition are; how the phenomena of paratexts evolved and developed in the Tibetan Buddhist cultural sphere; and whether some of the functions ascribed to Tibetan Buddhist paratexts can be corroborated empirically.
