    Research Interest/s

    The key areas of study in which I currently have a personal interest fit into the general aim of conceptualising the various factors underlying feeding behaviour, how these conspire to produce over-consumption and how we can intervene to restore the normal appetite regulatory processes. These are all crucial components in the study of obesity. In particular my research focuses on:

    1) Appetite regulation - Short-term and long-term neurobiological, metabolic and psychological mechanisms involved in controlling food intake, energy balance and metabolism.

    2) Obesity - The treatment of clinical obesity, particularly pharmacological,nutritional and behavioural approaches.

    3) Triggers of eating behaviour - The effect of external (such as food and food advertisements) factors on the initiation of feeding behaviour.

    4) Development of food preferences - Identification of a) mechanisms involved in, and b) factors influencing the development of enduring and healthy food preferences in infancy.
