Spalding specialises in 20th-century British art, biography and cultural history and her work includes essays, criticism and reviews. She curated the 2003 exhibition "John Piper in the 1930s: Abstraction on the Beach" at Dulwich Picture Gallery in south London.[3]
She has also written a study of poet Stevie Smith and a biography of John and Myfanwy Piper. When reviewing John Piper, Myfanwy Piper: Lives in Art, The Independent said of Spalding "At her scintillating best, she is both a brilliant encapsulator and shrewd summer-up; above all, an enthusiast and advocate whose wisdom makes you eager for her subject."[4]
