Tse-Hui’s research interests are in urban design. She is particularly interested in how infrastructures, technologies and cultures relate to urban forms. She uses a CCAT (Collective Coevolution of Actant Trajectories) framework to investigate these relationships and project how they may change in the future. She uses ethnographic and codesign game methods for her research. She is currently working on four research projects around water and sanitation infrastructures: CAMELLIA (Community Water Management for a Liveable London); Coevolution of Water Reuse Systems in Australia; Compost Communities at Spitalfields City Farm; and Sacred Rice, Dirty Cress and Urbanisation in Antananarivo, Madagascar.
