Our Lab
The SAM Lab seeks to understand the role of sleep and circadian regulation in metabolic homeostasis. Specifically, our team studies how sleep and circadian disruption impair metabolic tissues and whether improving the timing of behaviors such as sleep and eating can improve metabolic health and reduce disease risk.
Current Research Projects
Tissue-specific effects of sleep and circadian disruption
Tissue-specific effects of insufficient sleep
This project’s goal is to elucidate the underlying cellular mechanisms of metabolic impairments due to sleep and circadian disruption in people. The project is funded by K01 and R03 awards to Dr. Broussard from the NIH/NIDDK with additional support from the Center for Women’s Health Research, the NORC, and the CCTSI Co-Pilot programs at the University of Colorado Anschutz Medical Campus.
Co-Investigators on this project include: Kenneth P. Wright, Jr. (University of Colorado Boulder) and Bryan Bergman (University of Colorado Anschutz Medical Campus)
Physical activity and sleep and circadian disruption
Effects of physical activity on cardiometabolic impairments associated with insufficient sleep
The goal of this project is to determine the role of physical activity in mitigating metabolic impairments associated with insufficient sleep. Results from this study will help us identify potential countermeasures to the effects of sleep loss and associated circadian misalignment. The project is funded by a Sleep Research Society Foundation Career Development Award.
Co-Investigators on this project include: Kenneth P. Wright, Jr. (University of Colorado Boulder) and Ed Melanson (University of Colorado Anschutz Medical Campus)
Countermeasures to circadian misalignment
Countermeasures to sleep and circadian disruption
We currently have multiple ongoing studies to design and test countermeasures to sleep and circadian disruption including time-restricted eating and sleep extension, both funded by R01s from NIH/NIDDK.
Co-investigators for these projects include: Bryan Bergman and Janine Higgins (University of Colorado Anschutz Medical Campus), Kenneth P. Wright, Jr. (University of Colorado Boulder), and Sam Klein (Washington University).
