Goxwa was born in Valetta, Malta in 1961. She began painting at a very young age and enrolled at the Saint Martin School of Art. Years later, she moved to Boston where she attended Emerson College for film studies. In 1993 she was awarded fellowship at the Cité Internationale des Arts in Paris.
Her encaustic works on canvas defy categorization. Although she draws inspiration from ancient frescos, her paintings have a very contemporary feel. Goxwa explores all genres, yet all of her paintings have the same element of mystery and intrigue. In 1993 she had her first of many solo exhibitions. Since then she has shown in various cities including Paris, New York, Strasbourg and San Francisco. Goxwa currently resides in Paris and her exhibitions continue to draw crowds of admirers and collectors.
