Sarah E. Fraser (Ph.D. 1996, UC Berkeley; Associate Professor) teaches and researches primarily in Chinese painting with an emphasis on questions of artistic enterprise in medieval Buddhist art, early development of photography, and national identity formation through archaeological and ethnographic projects in the Republican period (1912-1949). Her books include Performing the Visual: Buddhist Wall Painting Practice in China and Central Asia, 618-960 (Stanford University Press, 2004), which concerns Chinese theories of spontaneity and workshop production in the middle period. Performing was recognized by the American Library Association's Choice award for Outstanding Academic book in 2004 and nominated for the College Art Association's annual award for best art history book in 2005. Fraser published an edited volume of essays on Buddhist material culture with the Shanghai Fine Arts Publishers, 2003, entitled Merit, Opulence and the Buddhist Network of Wealth, containing the Chinese proceedings of fieldwork and major conference she organized with Peking University in 1999-2001. She was the Chief Editor of wall painting and sculpture for the Mellon International Dunhuang Archive (MIDA), part of ARTstor––a new genre of web-based, art history research publication.
