Zeitzer Circadian Research Lab 

 The Zeitzer Circadian Research Lab studies novel ways to record and manipulate sleep and circadian rhythms. We are exploring the use of light, varying its intensity, spectrum, and temporal scales to maximize its utility as a countermeasure to the ills of the 24-hour society, including its impact on sleep, circadian rhythms, cardiovascular function, endocrine activity, balance, and cognition. We are also exploring new ways to deconstruct wrist activity (actigraphy), data that you might get from a Fitbit or Apple Watch, and the use of such data to inform us about a person's mental and physical health.
