Description of Research Expertise

Georgios Paschos studies the circadian regulation of metabolism. His research focuses on the metabolic consequences of circadian misalignment. Exposure to artificial light after sunset prolongs daily activities into the night and causes misalignment between the internal circadian clock and daily behavior. Georgios Paschos uses animal models of circadian disruption and proof-of-concept studies in healthy and obese volunteers to understand how the circadian clock regulates energy homeostasis, and how circadian misalignment predisposes to obesity.
