Sandra Githinji is an interior designer, educator and creative practice researcher undertaking a PhD in the School of Architecture and Urban Design at RMIT University. Her research investigates how creative practice can respond to the colonial legacies that shape diasporic relationships to home, belonging and place.

Central to her work is the development of Constellational Practice, a creative practice methodology that understands home as a dynamic network of relationships continually negotiated across people, place and time. Drawing on interior design and diaspora studies, Constellational Practice offers a relational framework for examining how home is remembered, reclaimed, reimagined and reconnected.

Through making, exhibitions, gathering and participatory design methods, Sandra explores how diasporic communities sustain connections to ancestral and contemporary homes while navigating displacement, migration and cultural transformation. Her research contributes to contemporary discussions on migration, spatial belonging, decolonial design practice and the evolving role of interior design as a discipline concerned not only with where people dwell, but how relationships to home are continually enacted.

Her work has been disseminated through exhibitions, publications and public programs nationally and internationally, including Nairobi, Perth and Melbourne Design Weeks, alongside featuring in design and architecture publications, most notably Making Space: Interior Design by Women. Alongside her research, she teaches within the Bachelor of Interior Design (Honours) program at RMIT University and maintains an independent design and curatorial practice, Sandra Githinji Studio.
