Olalekan Jeyifous (born 1977), commonly known as Lek (pronounced "Lake"), is a Nigerian-born visual artist based in Brooklyn, New York. He is currently a visiting lecturer at Cornell University, where he also received his Bachelor of Architecture in 2000. Trained as an architect, his career primarily focuses on public and commercial art. His work has been newly commissioned for the Reconstructions: Architecture and Blackness in America exhibition at the Museum of Modern Art in New York along with Amanda Williams, Walter Hood, and Mario Gooden. The exhibition explores the relationship between architecture and the spaces of African American and African diaspora communities and ways in which histories can be made visible and equity can be built.
