“Sleep, Aging, and Circadian Sleep Disorders”
Project 1: “Recurrent circadian disruption & pancreatic β-cell responsiveness in older people”
This Project will contribute to understanding the distinct metabolic risks from circadian disruption, laying the groundwork for research designed to develop therapies targeted to reduce the risk of obesity, metabolic syndrome and diabetes, and enhance the health and quality of life of older Americans whose circadian rhythms are disrupted by age-related changes, irregular schedules, and/or night shift work.
Project 2: “Adverse metabolic impact of sleep loss in older adults: insulin resistance”
This Project will contribute to understanding the mechanisms by which sleep loss impairs metabolism in older adults, contributing to future research to reduce the risk of diabetes, improve existing therapies, and enhance the health and quality of life of older Americans whose sleep is insufficient.
Roles: Project leader (Project 2) 2013-2015; Co-Investigator (Project 2) 2015-current: Co-Investigator (Project 1)

R01 HD073352      Hale (PI)      2013-2018
“Biopsychosocial determinants of sleep and wellbeing for teens in Fragile Families”
This study investigates the biopsychosocial and genetic determinants of adolescent sleep, and the extent to which differential sleep patterns and behaviors during childhood contribute to differences in obesity and cardiometabolic risk using the Fragile Families Study (FFS). The FFS is a national birth cohort study of health and development of children, with data collected at birth and ages 1, 3, 5, and 9, and, with recent NIH funding to locate and interview youths and mothers when the adolescents are age 15 (n~3,600). As an ancillary study to the parent FFS age 15 survey, this study aims to study adolescent physical activity and sleep and social/contextual predictors of these behaviors.

"Evaluating cardiometabolic and sleep health benefits of a workplace intervention"
Although the prevalence of “family-friendly” or “work-life” policies in U.S. workplaces has increased dramatically in recent years, few longitudinal experiments have evaluated the effects of work-family interventions on employee health outcomes.  The Work, Family and Health Study is an ongoing, randomized, controlled trial of an innovative workplace intervention to improve employee health. This Ancillary Study adds objective health outcomes in mid-level managers, a focus of the intervention, to evaluate the effects of this workplace intervention on managers' cardiometabolic and sleep health, and represents a unique opportunity to study the multi-level factors influencing health in the workplace.
Role: PI
Social Science Research Institute, Penn State, pilot grant 2014-2016 
“Female growth and development study 30-year follow up”
The lack of prospective longitudinal study has severely limited knowledge about specific mechanisms by which sexual abuse impinges on development over the life course. Studies of victims rarely span multiple developmental stages making it difficult to discern optimal intervention windows and developmental discordances that can impact adulthood competencies. The previous six timepoints have been collected and this study will focus on timepoints 7-8 which extend into the participants 30s and 40s and test the relative impact of early maldevelopment on later adulthood functioning. Capitalizing on the adulthood period affords inquiry into key outcomes (such as physical health outcomes and adulthood autonomy) that were not fully detectable earlier in development.

“Lifestyle & medication management to lower diabetes risk in severe mental illness”          
Serious mental illness (SMI), including chronic depression and post-traumatic stress disorder, are known risk factors for type 2 diabetes.
Role: Subcontract Principal Investigator

“Everyday Stress Response Targets in the Science of Behavior                    
The overarching goal of this project is to use an experimental medicine approach to develop an efficient, ecologically valid, within-person approach to measuring and intervening on the deleterious effects of everyday stress on meeting recommended levels of two
