Research Interests

The common MTNR1B (melatonin receptor 1B) risk SNP is associated with the pathogenesis of type 2 diabetes. The risk genotype has a significant adverse influence on the glucose tolerance and insulin secretion over time. The goal of my research is to determine the effect of circulating melatonin on glucose control, and their interactions with MTNR1B genotype. The mechanistic understanding of the role of melatonin and MTNR1B in glucose metabolism will provide insight into the interventions to prevent and treat type 2 diabetes.
