Research Interests

The over-arching theme of my research is to evaluate nutritional programming of reproductive function in livestock. In particular, the ability of cells in the brain to detect environmental conditions to determine if reproduction is a favorable event. My current work focuses on a population of cells within the arcuate nucleus of the hypothalamus, a nucleus associated with feeding behavior, energy metabolism, and reproductive function. These cells lie in close apposition to leaky vessels from the peripheral circulation as well as the cerebral spinal fluid. As a result of this close apposition, these neurons are at a prime location to monitor the energy state of an animal. Further, this population of cells is implicated in the regulation of the GnRH pulse generator, and thus the subsequent release of gonadotropins and reproductive function. This field of research is therefore relevant in the connection between nutrition and reproductive function and is applicable to animal production and human health.
