Born in Arecibo, Puerto Rico, in 1971, Aby Ruiz is a visual artist working with oil painting, drawing and installations. His work explores human nature in different situations in which human behavior is exposed. The body is the primary source of expression in highly charged compositions where sometimes an element of humor appears. The themes most developed by the artist are related to childhood, sexuality, mortality, innocence, violence, and tenderness and are addressed in undefined spaces and cropped images. Ruiz’s work has been presented in many international exhibitions in the United States, Panamá, Canada, and the Dominican Republic.

He is the recipient of several awards, and his work is held in many private and public collections in Puerto Rico such as Museo de Arte de Caguas, Museo de Arte Contemporáneo,  Museo de la Universidad Ana G. Méndez,  Ateneo Puertorriqueño, Museo de Arte de Bayamón, and Museo de Arte de Ponce.

Sin pena ni gloria, the artist’s first survey exhibition, encompassing more than two decades of painting, drawings and installations was inaugurated at El Museo de las Américas in 2023 followed by the publication of Aby Ruiz's monograph.
