Dr. Liu is currently an Assistant Professor at the Department of Nutrition, School of Public Health and Health Sciences, University of Massachusetts, Amherst, and an Adjunct Scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA), Tufts University. He completed his postdoc training from HNRCA and Tufts-New England Medical Center. He received his PhD in Nutritional Biochemistry from Auburn University with an additional MS degree in Statistics-Life Sciences. Before that he had a MS degree in Animal Sciences from China Agricultural University and a BS degree in Animal Science and Veterinary Medicine from Hunan Agricultural University. He is a reviewer for multiple research foundations and greater than 10 journals.
His research interests include: Diet and lifestyle are modifiable factors which play a prominent role in public health. His laboratory investigates how those factors and their metabolically-related gene variants interact to mediate the development of chronic diseases. Particularly, his research field centralizes on the nutritional modulation of the Wnt-signaling pathway as it tightly relates to many chronic diseases including cancer and obesity-associated medical complications. His laboratory uses cell culture, animal models and human biospecimens, biochemical and molecular techniques, as well as systems biology approaches to understand the etiology of human chronic diseases. The ultimate goal of his research is to translate our biological findings into dietary and lifestyle strategies to diminish the burden of chronic diseases in our society.
