My key research interests are:
1. Understanding why food insecurity (not knowing if you will have enough food to eat at your next meal) is associated with weight gain. With the number of people experiencing food poverty increasing, it is critical to identify the mechanisms underpinning this association. This will help with the development of potential countermeasures.
2. Looking for ways to promote sustainable diets. It is estimated that the global demand for food will increase by 60% by the year 2050. This demand far outstrips our current global potential for food production, particularly in terms of meat. It is essential we identify effective ways to change consumer behaviours and identify interventions.
3. Seeking to understand how and why environmental cues promote overconsumption. For example, the presence of larger portion sizes, distraction, or variety within meals (e.g. all you can eat buffets)
