Christoph is a PhD student at the Department of East Asian Studies, supervised by Hans van de Ven and Sheilagh Ogilvie since 2019. His work maps out the structure of the family in pre-industrial China and its implications for economic development. Key aspects of this project analyse how the family and wider kin group regulated property transmission between generations, migration, and market exchange. His work is a long-term study covering the period from ca. 1700 to 1950, which it investigates through a range of sources such as credit contracts, household division contracts, genealogies, and Japanese survey materials.
