Last month, Brown University/Bradley Hospital jointly received a US Patent (US 10850061) for a lighting system for circadian control and performance enhancement. 

The invention, developed from research led by Dr. Eliza Van Reen, an assistant professor of psychiatry and human behavior, consists of behavior- or illumination-sensing hardware and a lighting system that controls both lighting intensity and timing. The system could be used to treat jetlag and age- or disease-related circadian changes, to compensate for insufficiently illuminated workplaces, and to enable team work by individuals on divergent work/sleep schedules. The other members of Dr. Van Reen’s team are Gustavo E. Fernandes, Jingming Xu, and Mary A. Carskadon. Drs. Van Reen and Fernandes are founders of the startup Circadian Positioning Systems.
