Research Interest

Localization and function of biological clocks in vertebrates; light and food as entraining signals for circadian rhythms; obesity; sleep; reproduction.

--------------------------------------------------------------------------------

Current Research

Currently the research focus is on circadian clock gene expression in the CNS and in peripheral tissues relative to feeding time and on identifying humoral signals involved in gut-brain communication.
