Research Summary

Prior to coming to Monell, I conducted a series of controlled feeding studies testing how environmental factors, particularly portion size and energy density, and individual differences influence preschool children’s energy intake over time. At Monell, the goals of my research are to build upon this knowledge and develop a broader understanding of how individual differences contribute to preferences and appetite. I’m particularly interested in the relationship between a person’s genes and their taste preferences (e.g. sweet and bitter) and how this influences ingestive behavior.
