Mamadou Jean-Charles Tall, is a Dakar-based co- director of Tall Architectes et Associés, and has been a member of Dak’Art Biennale, he has served as president of the board of the Collège Universitaire d’Architecture de Dakar, an institution that he co-founded, and where he teaches and is director of the Masters of Architecture programme. Over several decades, he has cultivated an enduring concern for the development of an approach to bio-climatic architecture that is embedded in the transmission of sophisticated African knowledge systems. I sat with Jean Charles Tall virtually, to discuss his ongoing research on bio-climatic architecture and his African Mobilities project that surveyed diverse architectural styles and urban patterns in contemporary Senegal in Migrations and the Image of Space in Senegal (2018)
