Gili's career is marked by solo shows in London and New York and by contributions to seminal survey exhibitions at major venues such as the Hayward Gallery.
In recent years she has regularly shown in the Royal Academy Summer Exhibitions and notably in 2013 her sculpture "Ripoll" won the Sculpture Prize.
Katherine Gili's work is represented in the Arts Council Collection, Tate and other public and corporate collections in the UK, Switzerland and the USA.
Lord Foster selected one of her pieces to stand alongside the Cranfield University Institute of Technology Library which was designed by Foster Associates in 1992.
Gili was born in Oxford to father Joan Gili, Catalan publisher and translator, and Elizabeth (née McPherson or MacPherson), cookbook author, artist, and the daughter of a Scottish-Canadian missionary.
