Luke Norton, Ph.D.


Research Interests

My overall goal as a researcher is to combine physiological studies in humans and rodents with cutting-edge molecular and genomics approaches to improve our understanding of the pathogenesis of type 2 diabetes. In particular, I am interested in how novel type 2 diabetes candidate genes influence an individual’s risk for diabetes at the physiological and molecular/genomic level. My lab is also involved in novel studies designed to unravel the mechanism of action of novel and established type 2 diabetes medications in humans, animals and cells. We use a range of modern molecular and physiological tools to approach these questions.
