Current Research Activities:

My research interests center around feeding infants human milk. This includes both feeding directly at the breast and feeding expressed human milk from a bottle. 


National recommendations promote breastfeeding, a dyadic, dynamic, bidirectional, biological process. However, national breastfeeding surveillance surveys only measure infant’s dietary intake of human milk. It is currently unclear whether the many benefits of breastfeeding result from the composition of human milk, the mode of delivery of this milk or a combination of the two. This represents a critical gap in the literature. This first step towards filling this gap is creating a questionnaire tool that enables categorization of infants by how they are being fed as well as by what they are being fed.


I will use a combination of qualitative and quantitative research methods in a sequential exploratory design to develop a comprehensive infant feeding measurement tool that will enable categorization of infants by both source of nutrition and mode of feeding.
