Dr. Zeitzer is a circadian physiologist specializing in the understanding of the impact of light on circadian rhythms and other aspects of non-image forming light perception. He examines the manner in which humans respond to light and ways to manipulate this responsiveness, with direct application to jet lag, shift work, and altered sleep timing in teens. Dr. Zeitzer has also pioneered the use of actigraphy in the determination of epiphenomenal markers of psychiatric disorders.
Shifting Sleep Timing in Teens
The goal of this clinical trial is to determine whether a combination of a novel lighting
intervention and a behavioral intervention are able to increase total sleep time in
adolescents. The main questions this trial aims to answer are whether this combination
therapy is able to meaningfully increase total sleep time in adolescents, and do so over a
sustained period of time, and whether such a changes is associated with concomitant changes
in mood and cognitive performance.
