Areas of Interest
Dr. Sellayah's research aims to investigate the molecular mechanisms that govern fat (adipose) tissue development and function in the context of obesity. His specific focus is in:
- Investigating the developmental programming of brown adipose tissue thermogenesis.
- Assessing the Impact of maternal nutrition during development on offspring adipose tissue development and function.
- Elucidating the function of FTO in adipogenesis
- Establishing the therapeutic potential of metformin's effects on adipose tissue
- Evolutionary origins of obesity
