Sex-Dependent Central Regulation of Female Metabolism and Physiology

We are broadly interested in how the female brain uniquely controls a wide-range of sex-specific physiological responses. Currently, we focus on estrogen signaling in the medial basal hypothalamus (MBH) that includes the ventromedial hypothalamus (VMH) and the arcuate nucleus (ARC). Mouse models coupled with genomics and pharmacogenetics are leveraged to define the estrogen-sensitive neuronal modules important in locomotion, thermogenesis, reproduction and bone density. Our research program is highly relevant to age-related diseases in hormone deficient stages and to women’s health.

Understanding Intestinal Epithelial Biology

The intestinal epithelium comprises the human body’s greatest environmentally exposed surface and represents the largest sensory and endocrine organ. We utilize intestinal organoids and animal models to understand how the intestine senses and responds to regular and inflammatory stimuli. By investigating the molecular pathways involved, we aim to discover new ways to promote intestinal wound healing and modulate the signals contributing to visceral pain syndromes.
