Research Interests

Research in my lab is focused on understanding the role of nutritional factors that regulate metabolic activity. Some of the methods we employ are mouse models of diet-induced obesity, exercise (both chronic and acute), or gene knockout/overexpression to study nutrient mediated control of fatty acid oxidation, glucose uptake, and insulin signaling. Our lab also uses molecular and cellular biology methods to study nutrient mediated effects on transcriptional regulation of metabolism.

Current Research

Identification of bioactive food components that modify DNA transcriptional activity.

Epigenetic alterations of metabolic pathways though active DNA demethylation.
