Natural light controls our circadian clocks, synchronizing our activities with the day-night cycle. Neurobiologist Dragana Rogulja will explain how light affects our biology.  In the design of buildings, architects must balance peoples’ biological and psychological needs for daylight while considering factors like glare, thermal comfort, and energy savings.  Holly Samuelson will discuss how built environments can have an impact on the well-being of those who live and work in them.  They will then dialog and respond to audience questions.
