Circadian Regulation of Metabolism and Aging

This is an ongoing project at the FitzGerald lab, which aims to examine the following topics:

1. Exercise training, exercise tolerance, ageing and circadian biology of skeletal muscle.

2. Sexual dimorphism in the response to chronic circadian misalignment.
