My research involves investigating our relationship with nature. I practice permaculture (a sustainable design framework) to explore thoughtful, co-created, grassroots interventions that put care of the environment central to thinking and doing. I’m interested in what happens at the edges, the relationships between things, improvisation and spontaneity, deep understanding of nature, provocation and activism. Currently this involves the growth of an inspirational, urban, interactive permaculture space, on-campus at Edinburgh Napier university, where I work alongside staff, students, local and international communities to create self-sustaining, bio-diverse habitats and concepts that benefit people and the planet. Theoretically this work is largely anchored in phenomenology and uses digital technology as an explorative lens.
