Research Interests

We use large, observational data sets to query associations of circadian phenotypes, circadian misalignment, sleep, light, and work hours with health and longevity (with an emphasis on type 2 diabetes, obesity, cardiovascular disease and depression). Our work aims to identify modifiable risk factors in the realm of circadian and sleep research that can be leveraged for prevention strategies in real life settings.

Current interests include:

  1. Cardio-metabolic consequences of circadian misalignment and sleep deprivation
  2. Work hour characteristics, occupational safety, and tolerance to shift work
  3. Effects of sleep, and the mismatch between chronotype and work hours on mood and depression
  4. Quantification of light exposure in real life 
  5. Circadian phenotyping

See our detailed Circadian Rhythm and Sleep Epidemiology Lab website for the most up-to-date information about current research and other happenings in the lab.
