Elizabeth B. Klerman

Physician and circadian researcher; Professor of Neurology at Massachusetts General Hospital and in the Division of Sleep Medicine at Harvard Medical School, and Director of the Analytic and Modeling Unit in the Division of Sleep and Circadian Disorders at Brigham and Women's Hospital. Senior author of tubbs-mind-after-midnight-2022, and the only one of its five authors not based at the university-of-arizona.

Her work is clinical and biomathematical — modelling human circadian, sleep and neurobehavioral rhythms as much as measuring them. That is the background the Mind After Midnight paper's insistence on separating circadian phase from sleep loss comes out of: a modeller's objection to treating "tired" and "awake at 3am" as one variable.

She is the voice the ScienceAlert piece quotes, from a 2022 MGH research blog, and the quote is a request rather than a claim: "There are millions of people who are awake in the middle of the night, and there's fairly good evidence that their brain is not functioning as well as it does during the day… My plea is for more research to look at that, because their health and safety, as well as that of others, is affected."

ORCID confirmed by lookup, not inferred from the name.
