Working primarily in oil, his practice spans portraiture, still life, and landscape, defined by bold brushwork, heavy impasto, and physical mark-making.He rose to national prominence after winning the 2009 Archibald Prize and has since exhibited widely across Australia. His work is held in major public and private collections, including the National Portrait Gallery and the Art Gallery of New South Wales.
