Whitfield was the first director of the International Dunhuang Project, a position which she held for 24 years, from 1993 until July 2017.[1] In this capacity she was involved in research and cataloguing of Central Asian manuscripts at the British Library and elsewhere. She has a particular interest in censorship and forgeries from Dunhuang.[2] In an interview at the University of Minnesota in 2013, she talks about how she came to her interest in China and Central Asia and ways in which her interest in Central Asia has made her rethink Chinese history, regarding it as rather more fragmented and diverse than unitary narratives might have us believe.[3]
