Biographical details

Wendy Davis is an Associate Professor in Lighting, Director of Illumination Design, in the School of Architecture, Design and Planning at the University of Sydney. Prior to this appointment, she spent seven years as a Vision Scientist in the Lighting and Color Group at the National Institute of Standards and Technology (NIST) in the United States of America. Wendy earned her Ph.D. (2004) and M.S. (2001) degrees from the University of California, Berkeley in vision science after completing her B.A. (1999) in psychology and physiology at the University of Minnesota.

Wendy’s research focuses on lighting and colour, with a particular interest in novel illumination applications of emerging and next-generation energy efficient lighting technologies. With a colleague at NIST, she developed the colour quality scale (CQS) to evaluate the colour rendering properties of light sources for general illumination, leading to a 2009 United States Department of Commerce Silver Medal Award for Scientific/Engineering Achievement, ‘For developing measurement methods and technical standards to accelerate the commercialization of energy-efficient, solid-state lighting products.’

Wendy is involved in several professional and standards organizations, including the International Commission on Illumination (CIE) and the Illuminating Engineering Society (IES). She is a member of the IES Color Committee, was the chair of CIE technical committee 1-69 ‘Colour Rendition by White Light Sources,’ and was a member of the National Research Council’s Committee on Assessment of Solid State Lighting. Wendy served as a judge for Lighting for Tomorrow’s first ever solid-state lighting design competition in 2006 and was a technical reviewer for NASA’s lighting requirements in 2005. She has delivered over 45 invited and keynote presentations at lighting conferences and symposia in the United States, China, Taiwan, Australia, the United Kingdom, Colombia, and South Africa. Her work has been featured in the Washington Post and on the Australian Broadcasting Corporation’s (ABC) Radio National, as well as numerous smaller media outlets.
