Professional Statement

My research program seeks to understand how dietary carotenoids impact human health. Carotenoids are a class of colorful orange, red, and yellow compounds found in fruits and vegetables. Some carotenoids, such as beta-carotene and alpha-carotene are converted to vitamin A in the body- and therefore play an important role in development and health. Other carotenoids, such as red lycopene and yellow lutein, are not pro-vitamin A, but may play a role in cancer prevention and promotion of cognitive functions, respectively.

We engage a translational research approach. We are currently studying how the mechanisms by which carotenoids are absorbed from foods, distributed throughout the body, and metabolized using in vitro and animal models. We are interested in studying how human genetic polymorphisms impact the levels of carotenoids found in the body. In addition, we are studying the molecular impacts of carotenoids in the body to better understand how carotenoid consumption may reduce the risk of disease in children and adults.
