Translational Sleep & Circadian Sciences Program

As the population of older Americans increases, a major public health priority is to identify approaches to optimize healthy aging and to limit the disabling effects of chronic diseases and Alzheimer’s disease and related dementia (ADRD) in underserved communities. An important focus of the Translational Sleep and Circadian Sciences Program at NYU Langone’s Center for Healthful Behavior Change is to ascertain whether the disproportionate burden of ADRD in minority populations can be attributed to sleep deficiencies, including poor sleep, sleep apnea, and circadian misalignment. We aim to develop early intervention strategies to curb the expanding health burden on minorities, especially that resulting from inadequate access to personalized medical and psychological care.

Our program, supported by a National Institutes of Health (NIH) K07 award, aims to address the U.S. Department of Health and Human Services Strategic Goal 3 of strengthening “the economic and social well-being of Americans across the lifespan.” Our goal is to foster rich cross-campus collaborations between investigators in various disciplines at NYU Langone, NYU, and other premier institutions, to maximize the rigor and impact of innovative approaches to reducing disparities in the brain health of vulnerable communities. We also aim to develop new curricula and research projects in translational sleep and circadian sciences.

Reducing disparities in cardiovascular and brain health is an important area for translational research, and mentoring junior investigators in the area of translational sleep and circadian sciences is paramount. We incorporate recommendations from the National Alzheimer’s Project Act and draw from NIH-sponsored studies identifying mentorship as the most important factor in fostering successful research careers.

Our Vision and Mission

The vision of the Translational Sleep and Circadian Sciences Program is to serve as a collaborative learning laboratory and a university-wide resource to stimulate, support, and evaluate high-priority ADRD research with a special focus on low-income and underserved communities. We have a three-part mission:

  • to amplify, through core faculty, concurrent NIH-funded research in understanding the mechanisms underlying racial and ethnic disparities and testing multilevel interventions (patient, clinician, and community) to promote optimal aging and disease management among people living with Alzheimer’s disease
  • to mentor 12 junior scientists who are pursuing academic careers in aging research from a variety of NYU-based postdoctoral programs, with special effort made to recruit women and underrepresented minorities
  • to implement innovative research strategies in translational sleep and circadian sciences to reduce health disparities in ADRD and disseminate evidence generated from the program into clinical and public health practice and policy

Our Core Faculty Mentors

A wide array of nationally and internationally recognized NYU Langone and affiliated faculty, as well as faculty from other premier local and regional institutions, participate in our program. Our interdisciplinary group includes practicing physicians with expertise in clinical research and investigators conducting research in the areas of community-based population health, health disparities, sleep medicine, Alzheimer’s disease, dementia, and cardiovascular disease prevention. Many of our mentors drive pioneering studies in their respective fields.

She also has expertise in cardiovascular disease and geriatric conditions, particularly cognition and falls, in older adults.

Mony J. de Leon, EdD

Specialization: imaging; dementia
Dr. de Leon is a professor of psychiatry at Weill Cornell Medical College where he founded the Center for Brain Health-Neuroimaging Laboratory. The center employs diverse PET tracers, high-field MRI, and cerebrospinal fluid and plasma biomarker assays in multiple conditions associated with increased risk for cognitive decline: chronic inflammation, traumatic brain injury, hypertension, and familial and genetic risks for dementia.

Silvia Fossati, PhD

Specialization: Alzheimer’s disease; cerebral amyloid angiopathy; traumatic brain injury; post-traumatic stress disorder
Dr. Fossati, an associate professor of pharmacology at the Lewis Katz School of Medicine at Temple University, is the associate director of the Alzheimer’s Center at Temple.

Lidia Glodzik, MD, PhD

Specialization: Alzheimer’s disease biomarkers; neuroimaging
As an associate professor of psychiatry at Temple University and co-director of the Alzheimer’s Center at Temple, Dr. Glodzik focuses on arterial spin labeling perfusion and on applying new imaging techniques to evaluate metabolic changes in the hippocampus. She also assesses the value of cerebrospinal fluid biomarkers in early diagnosis of Alzheimer’s disease.

Girardin Jean-Louis, PhD

Specialization: sleep and circadian research; aging
Dr. Jean-Louis is a professor of population health and psychiatry at NYU Langone and director of the NIH-funded Program to Increase Diversity in Behavioral Medicine and Sleep Disorders Research (PRIDE) Summer Institute. He has been involved in several key NIH-funded studies, leading to over 300 publications, primarily in sleep and cardiometabolic diseases, circadian rhythm, aging, and health equity. Consistent with the National Institute on Aging Academic Leadership Award’s goals, Dr. Jean-Louis leads the NYU Sleep Disparity Workgroup to develop innovative approaches to elucidate the role of sleep deficiency (for example, poor sleep, sleep apnea, and circadian misalignment) among older adults in communities at risk of developing ADRD.

Olugbenga G. Ogedegbe, MD, MPH

Specialization: hypertension; cardiovascular disease
Dr. Ogedegbe, a physician and professor of population health and medicine, is a leading expert on health disparities research, whose work focuses on implementing evidence-based interventions for cardiovascular risk reduction in minority populations. He is the principal investigator on numerous NIH-funded projects and has expanded his work internationally to sub-Saharan Africa to strengthen research capacity and reduce the burden of noncommunicable diseases.
