Research Summary
My research interests are focused on the hypothalamic regulation of energy homeostasis and the development of treatments for obesity. I am interested in the molecular mechanisms by which several hormones discovered over the past few years control food intake. I am studying the neuroendocrine changes that occur with weight loss in both rodent models and obese humans.

Research Activities
Animal Studies:
§ Examining the role of agouti-related protein (AGRP) in regulating food intake. AGRP is a hypothalamic peptide that increases food intake in rodents by antagonizing the action of alpha-melanocyte stimulating hormone (a-MSH), a peptide that acts to decrease food intake, at melanocortin receptors within the brain.
§ Examining the role of the dopaminergic system in energy homeostasis and insulin sensitivity.
§ Using rodent models to design effective weight loss strategies for future use in humans. One such study involves combination treatment with naloxone (an opioid antagonist) and leptin (a peptide hormone produces by adipocytes).
Human Studies:
§ Analysis of hormones involved in energy homeostasis before and after bariatric surgery (gastric bypass and banding) and implantation of a gastric pacemaker, an experimental procedure used for weight reduction.
§ Exploration of different therapies for the treatment of hypothalamic obesity.
