Jaray taught at The Slade School of Fine Art, UCL, from 1968 until 1999. Over the last twenty years Jaray has completed a succession of major public art projects. She was made an Honorary Fellow of RIBA (Royal Institute for British Architects) in 1995 and a Royal Academician in 2010.
Jaray's work is heavily influenced by the Renaissance architectural spaces she encountered on her travels in Italy. These vistas were formative for the development of her distinctive technique. In these ceilings she saw how simple lines interacted to transform space, inducing emotional responses. Her work investigates the quality of effects that geometry, pattern, repetition and colour have on space. Ultimately, she seeks to expose the underlying principles of architectural perspective - namely, the way in which the history of decoration and patterning is embedded in all that we see and how we perceive it.
