Functional Foods and Human Health Research Laboratory


Personal Statement:

The primary goals of our research program are to identify and critically examine functional foods, bioactive compounds, dietary supplements, and other dietary interventions that can effectively prevent and/or improve both established and emerging risk factors for chronic diseases associated with aging such as cardiovascular disease and cancer. This is achieved primarily through conducting clinical research studies and utilizing novel techniques aimed at obtaining mechanistic insights. A population of particular interest is postmenopausal women, as the physiological changes that occur in the menopausal transition and postmenopausal period have been shown to accelerate the development and progression chronic diseases and conditions.
