Welcome

Our lab studies the neuroendocrine control of reproduction. We’re particularly interested in how circadian rhythms affect fertility.

Our Research

Neuroendocrine circuitry

We study the development and maintenance of the hypothalamic circuits that regulate reproduction, particularly GnRH and Kisspeptin neurons.

Circadian control of reproduction

We study the contribution of the circadian rhythms to ovulation and the maintenance of fertility.

Suprachiasmatic nucleus heterogeneity

We study determinants of functional diversity among neurons in the master circadian pacemaker

Right: Gonadotropin-releasing hormone (GnRH) neurons in the preoptic area.
