Artist who studied, 1983–4, at the School of Art in Cambridge, where she lived, gaining a fine art honours degree at Central St Martins School of Art, 1984–7. In her wide-ranging work, Sinclair was “intrigued by the natural process of reduction and regeneration; by the effects of natural forces, such as water, on wood, stone and metals…. There is often great beauty in naturally eroded materials”. Her many group shows included Johnson’s Wax Kiln Gallery, Farnham, 1990; Postmorality, Kettle’s Yard, Cambridge, 1991; Cambridge Society of Painters and Sculptors, from 1992; Broughton House Gallery, Cambridge, 1997; and Wilson Stephens Fine Art, 2000.
