Research Summary

The Taylor Lab investigates the molecular mechanisms regulating mitochondrial function and their relationship to disease. Our approach is multidisciplinary. We employ diverse experimental models as necessary to solve fundamental problems in metabolism. We have specific expertise in molecular genetics and metabolomics. We have ongoing projects on diabetes, cancer, and neuroscience.
