"These are the fastest schedules that have ever been proposed," said Olivia Walch, a PhD student at the University of Michigan who designed the app, called Entrain. "Our schedule takes what could be 12 days of adjusting down to four."
The mathematical model was created by Daniel Forger, a biological mathematician who has been studying circadian clocks since the 1990s. A paper describing his research was published Thursday in the journal PLOS Computational Biology. The Entrain app was released the same day.
Forger admits that the schedules his model spits out may sometimes seem counterintuitive, but intuition, he says, is not the point.
