Biography

Current Research

Neural mechanisms of Circadian Rhythm Regulation

The primary stimulus for setting the circadian clock is the environmental light cycle (day/night). Photic information communicated from the eyes to the suprachiasmatic nucleus in the hypothalamus through the excitatory amino acid neurotransmitter glutamate. The inhibitory amino acid neurotransmitter, GABA, acts to oppose the actions of glutamate. In addition to these, many other neurotransmitters and neuromodulators have effects on circadian rhythms. Our lab seeks to define the mechanisms by which a small group of cells located in the suprachiasmatic nucleus of the hypothalamus generate rhythms of physiology and behavior, and how these rhythms are modified by environmental and physiological stimuli. We use a wide variety of techniques, including microarrays, real-time PCR, in situ hybridization, immunohistochemistry, intracranial microinjections, and analysis of behavioral rhythms.

Topics currently under investigation in the lab include:

  • How the timing of feeding influences clock function.

  • The role of cannabinoids in regulating circadian rhythms.

  • Differences in gene expression in subregions of the suprachiasmatic nucleus and how those differences relate to function.

  • How disruption of circadian rhythms can affect fertility.
