Sidse is a Research Fellow with years of experience in ageing research with a particular focus on participatory research and co-design with older people.

At the Design Age Institute, Sidse is working on the demand side exploring the many and diverse needs and aspiration of the UK ageing population.

Prior to joining RCA Sidse worked on a collaborative research project in Copenhagen focusing on co-designing age-friendly cities and communities with older people. Through her research, she is committed to bringing the resources and expertise of older people into the design discipline.

She holds a Master of Arts in Architecture from Aarhus School of Architecture (2011) and a PhD degree from the Royal Danish Academy of Fine Arts, Copenhagen (2020).

More information

Sidse’s research interests include participatory and collaborative practices and how design and design processes can serve as enablers that give older people a voice when shaping the future. She is committed to nuancing and updating the ‘ageing image’ and to bring the many resources of the ageing population into the design discipline.

Sidse has a great interest in the built environment and the spatial aspects of growing old, including social and physical dimensions of homes, neighbourhoods and public spaces. In her PhD, she explored co-design of age-friendly cities and communities with a specific focus on the methodological investigations and the role of participatory design methods in practice-based community design with low income older people.

Design Age Institute, 2020

The Design Age Institute aims to amplify the voice of people as they age and ensure their inclusion in the design of new products and services, and through this support a better functioning marketplace.

Collaborating partners include Oxford Institute of Population Ageing at Oxford Univeristy, National Innovation Centre Ageing at Newcastle University and the Design Museum.

Ageing in a Vertical City, 2017

The project focused on design opportunities for future generations of older people in Hong Kong, including care home settings. The project was carried out in collaboration between Helen Hamlyn Centre for Design at RCA and The Hong Kong Polytechnic University (PolyU)
