My interests related to the Neurotherapeutics Institute fall in three areas:  
(1) My major area of interest is the understanding of circadian rhythms in mammals. Circadian rhythms are generated by a known anatomical site, the suprachiasmatic nucleus, and we now know a fair amount about the molecular mechanisms underlying its oscillation. Mouse circadian rhythms have been used as an output/ assay system for demonstrating genetic regulation of behavior, and reversible effects of inducible gene manipulation on behavior, and I believe that this system holds great promise for optimizing transient gene disruption and for assessing the duration of gene therapy in vivo.

(2) I have new research interests in myelination.

(3) Involvement in the Neurotherapeutics Institute will help keep me informed of cutting-edge neuroscience research on campus, which is important to me in my role as Director of the Graduate Program in Neuroscience.
