Her research interest is on social interactions between mothers and their infants. One of her research topics is whether and how mothers’ emotional experience in parenting, such as separation anxiety, contributes to their sensitivity and responsiveness to infants’ social signals during social interaction. She is also interested in investigating the outcomes of mother-infant interaction that seek to understand the linkage of the quality of social interaction between mother and infant to later child compliance and social understanding in toddlerhood and preschool age.
