Dan Walsh studied at Philadelphia College of Art and Hunter College. Walsh explores perceptions of color and space through the use of linear, but irregular, geometric patterns. The artist allows his freehand strokes to deviate from formal perfection and introduce suggestions of living forms. His juxtaposition and layering of color creates depths and volumes that cause his shapes to hover over or recede into the picture's surface.His work has been exhibited in national and international galleries and institutions, including a retrospective at Paula Cooper Gallery, New York; the New Museum of Contemporary Art, New York; and PS1 Contemporary Art Center, Long Island City. His prints and limited edition books were the subject of a solo exhibition at the Cabinet des Estampes du Musée d’Art et d’Histoire, in Geneva, Switzerland. He was also included in the Ljubljiana Biennial, Slovenia, and the Lyon Biennial of Contemporary Art, France. Walsh was included in the 2014 Whitney Biennial.
