Dr. Sam Virtue

About me

I am research associate in the TVP Lab.

Research Interests

My main focus is on metabolic flexibility. I study how using the wrong nutrients at the wrong times leads to metabolic disease, focusing on how adipose tissue controls nutrient storage and supply to other organs. I also study fatty acid remodelling and how it impacts on physiology and metabolic disease, and I also have a long-standing interest in improving the translatability of mouse physiology to humans.
