Research Interests
My research interests include both basic and applied aspects of sleep research and circadian physiology. Much of my work has focused on understanding the effects of sleep and circadian rhythms on human metabolism, including energy, lipid, and glucose metabolism. I have also examined the effects of chronic sleep loss and circadian disruption on sleep structure and neurobehavioral performance, as well as how the COVID-19 pandemic has changed sleep and daily rhythms globally. My other research interests include applying artificial intelligence to improve the diagnostic process for detecting and treating sleep disorders, and pursuing novel treatments for sleep and circadian rhythm disorders such as the shift work disorder.

  1. (Kirsi-Marja Zitting) Jan 15, 2020 - Jan 14, 2022
    The American Academy of Sleep Medicine Foundation
    Deep neural network model for automatic detection of sleep-disordered events from out-of-center level 3 sleep tests
    Role Description: The goal of this study is to develop a deep neural network model to automatically detect apneas and hypopneas from the electrocardiogram signal and apply his technique to the scoring of out-of-center sleep tests (OCSTs).
    Role: Principal Investigator
  2. (Kirsi-Marja Zitting) Jul 1, 2019 - Jun 30, 2020
    Eleanor and Miles Shore 50th Anniversary Fellowship Program for Scholars in Medicine (Harvard Medical School)
    Early vs. late time restricted feeding, circadian timing, and chronotype in overweight and obese adults: Impact on weight loss and cardiometabolic health
    Role Description: The goal of this study is to test in overweight and obese free-living adults the impact of early time-restricted feeding vs. late-time-restricted feeding on weight loss and cardiometabolic health, and to examine whether individual chronotype mediates these effects.
    Role: Principal Investigator
  3. (Kirsi-Marja Zitting) Jun 1, 2019 - May 31, 2020
    William F. Milton Fund, President and Fellows of Harvard College
    Automatic behavior in musicians
    Role Description: The goal of this study is to determine in highly trained musicians whether there is evidence that automatic behavior (AB), which occurs during highly learned behaviors such as playing an instrument and is characterized by a continuation of the behavior with amnesia, is due to local sleep where small areas of the brain go offline.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
