From leading groups in documenting rural and urban infrastructure to building green structures, Rubana has experience working in the conceptual, design and practical side of architecture. She believes that the best way to reduce the effects of climate change is focusing on resilient design, reduction of consumption, and restorative policies. Rubana has spent 5 months living and learning in a zero-waste community in Auroville, building prototypes of completely green buildings that capture carbon, volunteering, and creating awareness about sustainable and vernacular design. She is constantly looking for new architecture to stare at, owns a dog named Timon, and loves the Lord of the Rings series.
