Research Description: 

Diet and lifestyle are modifiable factors which play a prominent role in public health. My laboratory investigates how those factors and their metabolically-related gene variants interact to mediate the development of chronic diseases. Particularly, my research concentrates on the nutritional modulation of the Wnt-signaling pathway as it tightly relates to many chronic diseases. Currently, my laboratory focuses on 1) nutritional epigenetics and 2) obesity and inflammation in terms of the regulation of Wnt pathway and the prevention of cancer. We utilize cell culture, animal models and human biospecimens, biochemical and molecular techniques, as well as nutritional informatics and functional genomics approaches to understand the etiology of human chronic diseases. We explore the health benefits of nutrients and natural medicinal components with epigenetic and/or anti-inflammatory properties. The ultimate goal of my laboratory is to integrate our biological findings with dietary and lifestyle strategies to diminish the burden of chronic diseases in our society.
