With a background in fine art and visual communication, recognised by an award from the International Society of Typographic Designers, his work reflects a deep connection to urban environments and communities.

His work has been presented at art fairs such as INK Miami, Art on Paper NYC and EXPO Chicago, and his collaborations include institutions such as the Irish Museum of Modern Art (IMMA), the Palais de Tokyo in Paris or even the Sydney Opera House and the Wembley Stadium. To date, his work includes murals in various countries, including Ireland, the UK, Denmark, Uganda, the USA and now Portugal.

He has exhibited solo at prestigious galleries such as Rhodes Contemporary Art and Lazarides Gallery, the gallery that represented Banksy. His awards include several honours from the Arts Council of Ireland, including the ‘Agility Award’. He currently leads Atelier Now, a creative space in Dublin dedicated to contemporary art and artist residencies.
