Professor, Human Development and Family Studies


I specialize in development during infancy and early childhood and conduct research in two general areas. The first pertains to the emergence of jealousy. These studies explore factors that underlie the ontogenesis of sensitivity to exclusivity as well as those responsible for individual differences in jealousy’s presentation and differentiation along typical and atypical trajectories. The second pertains to the breastfeeding dyad. These entail multidisciplinary approaches involving teams of researchers from TTU and TTUHSC toward understanding and enhancing health and cognitive benefits for the breastfed infant during the first year of life.
