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, my research builds on my dissertation work, but shifts the focus to looking at both children and their mothers as a dyad, sweet taste phenotypes, and new measures of dietary habits that incorporate what people like to eat.
