Biography

The goal of my research is to elucidate the interactions between host genetics, dietary intake, and gut microbes in order to benefit host health. My lab's current projects focus on  the amylase locus, a result of gene copy number variation, which encodes an enzyme involved in starch degradation. Amylase gene copy number has been associated with glucose homeostasis, but knowledge of the underlying mechanisms is incomplete. We seek to determine the association of this locus with host health status. Additionally, we are interested in microbial involvement in starch digestion. Our research is interdisciplinary; we combine knowledge from genetics, nutrition, physiology, microbiology, and computational biology. Our findings could help to develop a systems biology approach to personalized nutrition to assist in treating metabolic disorders or decreasing disease risk.
