Oneika attended the Edna Manley College in Kingston, Jamaica. from 1999 to 2003 where she completed a diploma in the Painting Department. In 2003 she left for studies at Goldsmiths College in London in the Centre for Cultural Studies. While at Goldsmiths, Oneika began to integrate her deep interest in combining the practice of Painting with New Media. Characters and stories are the basis of her work. Many of the stories are imaginings, re-inventions and re-readings inspired by experience and locations as well as romanticized memories from literature, cartoons, picture books and fairy tales, magazines and other media. Her current work plays with sound, drawing and animation to convey and facilitate experiences and story. She has recently completed the Doctoral Course at Kyoto Seika University, Japan concentrating on Animation in Contemporary Art.
