My research looks into the institutional, military, and fiscal structures of imperial China from the Song to the Ming period, focusing particularly on how the Mongols impacted the state's employment and retention of personnel. My secondary research interests includes comparative state building strategies of nomadic conquest dynasties, the causes and impact of military uprisings, and salaries and stipends as a component of state payments and their relationship with the political and fiscal structures of the empire. I received my BA from UCLA and my MPhil from the Hong Kong University of Science and Technology.
