She is an applied social researcher who has experience of working on activities that bridge research, evaluation and engagement. Her research interests focus upon knowledge production, participation, social sustainability and health and wellbeing, particularly understanding the relationships between people, their local environment and decision-making processes. Tse-Hui Teh is a lecturer in urban design and planning at the Bartlett School of Planning. Her research is focussed on how collectives of people, things and other species can coevolve so that people can live in sustainable ecosystems. She uses interviews, discussion groups, workshops and document analysis in combination with design and co-design to understand how the relationships between people, things and other species have changed and are likely to change in the future. Her current projects look at water reuse, water quality, vacuum flush and dry toilets.
