Video interview with Mark Rea: Light and human health

Solid-state lighting and the discovery of a new photoreceptor in the brain have stimulated the study of how light impacts biological systems.
15 March 2011, SPIE Newsroom. DOI: 10.1117/2.3201103.01
Mark Rea is professor of cognitive science and director of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute (Troy, NY).

The LRC offers a variety of graduate programs and professional education in a wide range of lighting topics, from components, systems, and design to the biological, physiological, and psychological aspects of light.

Mark Rea's research interests include vision, lighting engineering, and human factors. He studies the effects of light and circadian disruption on breast cancer, the effects of daylight on worker productivity in commercial offices, and development of new metrics to improve the acceptance of energy-efficient lighting technologies. He also studies how to reduce market barriers to widespread use of energy-efficient lighting controls.

He was the recipient of the Illuminating Engineering Society Medal in 2000 for "technical achievement that has conspicuously furthered the profession, art or knowledge of illuminating engineering."

He was interviewed for SPIE Newsroom at SPIE Photonics West 2011, where he gave an invited paper entitled "Human health and well-being: promises for a bright future from solid-state lighting."
