Research Interests

Our research focuses on factors that influence development and maintenance of adaptive resilient responses to stressors. We have studied stress responding for many years from a variety of perspectives, including behavioural, hormonal and neural in both non-human animal models and humans. The factors we are most interested in that influence development of adult stress responding are those that occur during early life, such as prenatal stress and enriched postnatal environments. We are also interested in maintenance of a healthy stress response, which is influenced by factors such as age and sex. We are presently invesigating the interaction between the gut and the brain in the development and maintenance of a healthy stress response.
