Research in the Jansen lab focuses on the role of biological rhythms in the expression of motivated behaviors, endocrine physiology and metabolism.  Humans and other animals have internalized geophysical properties such as the daily light:dark cycles and seasonal changes in daylength into their physiology to enable synchronization with the environment.  Disruption of this process either through jet-lag, shift work or gene mutation can have a negative impact on human and animal physiology.  Nevertheless, evidence of arrhythmicity or loss of synchronization in some animals suggests that rhythms may be abandoned under certain conditions as part of their normal annual cycles.  Our goal is to better understand the mechanisms by which rhythms, or the lack thereof, can maintain an adaptive physiology in animals and man.
