Born in 1970 in Chachoengsao, Thailand, Utai initially studied painting at Silpakorn University. After developing an interest in the illusionary effects of dimensions and distance, Utai began working more heavily in sculpture. His work largely consists of abstract wooden sculptures that he painstakingly handcrafts without electrical tools. Influenced by Buddhist and Taoist philosophies, Utai frequently explores themes of emptiness, perception, and impermanence in his artworks. He has exhibited widely and received a number of accolades, including the third prize in sculpture at the 51st National Exhibit of Art in Bangkok (2005), and the second prize and Krung Thai Bank Award at the 52nd National Exhibition of Art in Bangkok (2006).
