Associate Professor Spencer's research focuses on metabolism, stress, inflammation and satiety signalling, including early life programming of the obese brain.
The early life environment is fundamentally important in dictating the type of adult we become. In our laboratory we investigate how the early life environment influences our physiology to change the way our bodies process food, stress, and challenges to the immune system, and whether these changes are permanent or reversible.
- How does overfeeding in early life influence long-term neuroimmune function?
- How does overfeeding in early life influence the stress axis long-term?
- How does early life diet influence puberty onset and the ability to reproduce?
- What is the role of ghrelin in stress?
- What are the roles of ghrelin and leptin in programming early brain development?
- How are teens more susceptible to the effects of a high fat and low exercise lifestyle than adults?
