The best art shows this week – From modernist abstracts to sculpture, installation, neon and video

Rodney Graham at Imma, Dietrich Blodau retrospective and Emma Finucane’s work inspired by nursing and midwifery

Rodney Graham: That's Not Me Irish Museum of Modern Art, Royal Hospital, Kilmainham, Dublin  Until February 18 imma.ie

Canadian artist Rodney Graham is the joker in the pack of an influential group of Vancouver artists who emerged in the 1980s, centering on conceptual photographers including Jeff Wall and Stan Douglas, both previously seen at Imma. With a satiric edge, Graham's work – lightboxes, film, music, and more – often undercuts the history and conventional perceptions of modern and contemporary art.

Dietrich Blodau: A Life of Observations The Hunt Museum, Custom House, Rutland St, Limerick Until January 14 huntmuseum.com

Dietrich Blodau came to Ireland to set up the print department of Limerick School of Art and Design, which he then headed for many years. An admirable, independent spirit, he was still in his early 30s when he arrived in Limerick, he was struck by the historic fabric of the city and many of his works respond to his new environment with great skill and veracity. The title is accurate: he is an inveterate, careful observer, and his scope had widened over the years to encompass the landscape beyond the immediate, built environment. This retrospective show marks his 80th birthday.
