Research Interests

I am interested in how neural areas receiving output from the suprachiasmatic nucleus of the hypothalamus (the circadian “clock” of the mammalian brain) differentially contribute to daily rhythms of sleep and wakefulness, locomotor activity, and body temperature.

Building on my doctoral work, I am also interested in how differences in this circuitry may account for phenotypic differences seen across development and between species.
