Launch of the Laboratory for Sleep and Digital Health Website
We are thrilled to announce the launch of our new website for the Laboratory for Sleep and Digital Health! The site will serve as a hub for our latest research, projects, and innovations in sleep, circadian rhythms, and digital biomarkers for brain health. Stay tuned for updates, publications, and resources as we continue to advance the field and promote healthy cognitive aging. Visit us at LSDH to learn more! Our mirror site, hosted on GitHub, will remain live for continued access.

Dr. Li Teaches Introductory Statistical Data Analysis with MATLAB at International Summer School
Our PI Dr. Li recently taught a course during an online international summer school program hosted by China Pharmaceutical University. The 16-hour, one-credit course introduced students to statistical analysis using MATLAB, offering hands-on experience with fundamental techniques and tools. Dr. Li’s expertise in computational data analysis provided students with valuable insights and practical skills in statistical analysis. Congratulations to Dr. Li for contributing to this enriching educational experience!
New Article Published in Alzheimer’s & Dementia
A measure derived from actigraphy for the fractal fluctuation patterns of rest-activity delineates cognitive resilience. It was associated with cognitive decline after regressing out ten neuropathologies related to dementia, explaining an up to 5% variance in cognitive decline on top of and beyond about 35% variance explained by pathologies.
New Gift Fund
The Li Lab is pleased to accept a gift from a generous philanthropy donor. The fund will be used for wearable sleep detection advancement.
New Role as Assistant Editor in Journal of the American Heart Association
Dr. Li was appointed to an Assistant Editor in the esteemed American Heart Association (AHA) journal – Journal of the American Heart Association. In 2024, the Journal expanded its Early Career Program to include a group of Assistant Editors. Dr. Li is one of the ten newly recruited Assistant Editors in this journal.
Serving on the Editorial Board of SLEEP
From 2024, Dr. Li started serving on the Editorial Board of SLEEP, the most regarded journal in the field of sleep medicine and the No. 1 journal in sleep researchers’ ranking of sleep journals.
New Article Published in Nature Communications
Frailty, or age-related decline in physiological function, is a common condition in older populations that increases their vulnerability to adverse health outcomes. We found a longitudinal association between disturbances in daily patterns of rest and activity, or circadian rest-activity rhythms, and higher risk of occurrence and progression of frailty over time..
Establishing A New Lab at Mass General Hospital
Dr. Li just started his new role as an Assistant Professor of Anethesia at Department of Anesthesia, Critical Care and Pain Medicine (DACCPM) at Massachusetts General Hospital, Harvard Medical School. He will be leading a new research lab within the DACCPM.
New Article Published in Annals of Neurology
Delirium is a complex neurocognitive syndrome suspected to be bidirectionally linked to dementia. We found that 24-hour daily suppression in rest activity rhythms, fragmentated rhythms, and potentially delayed acrophase were associated with delirium risk. Subsequent progression to dementia was more likely in delirium cases with suppressed rhythms.
Dr. Li Awarded the 2022 Department of Medicine Early Career Mentoring Award
Dr. Peng Li is award the 2022 Early Career Mentoring Award by the Department of Medicine (DOM), Brigham and Women’s Hospital. The Early Career Mentoring Award was established in 2011 to recognize the efforts of early career faculty who demonstrates effective mentoring through guiding and encouraging the career development of DOM residents, fellows, and/or faculty.
