In his installations he works with cocoa and coal jute sacks, a result of his investigation of the conditions of supply and demand in African markets. Torn, written on and transformed, the stamp PRODUCT OF GHANA still adorns the old sacks. Although his works provide a critical reflection of the value system inherent to his material, they are presented at Ghanaian markets as well as galleries.

He graduated in Painting and Sculpture from Kwame Nkrumah University in Kumasi and was a participant of the 2015 Venice Biennale.
