Shuyi Yin is an architectural historian and preservation scholar whose work examines heritage documentation, material culture, and media history. Her research traces how architectural and urban heritage has been recorded, measured, visualized, stored, and governed through changing documentation technologies, from nineteenth-century survey photography and photogrammetry to the institutional standardization of photographic archives and early digital systems. She received her PhD in Historic Preservation from the Columbia University Graduate School of Architecture, Planning, and Preservation. Her current book project examines documentation technologies as material infrastructures of authority, arguing that photographs, measured drawings, survey forms, technical standards, and data systems do not simply record heritage sites but help produce the evidentiary and institutional frameworks through which they become legible, administrable, and worthy of preservation.
