Main Focus

I am interested in food cognition and food behaviours. In particular my research investigates how infants and young children learn what is edible and what is not, both individually and with the help of others. My research encompasses a broad range of theoretical perspectives, and I use methods from developmental psychology to evolutionary psychology to examine these questions in early childhood and infancy.
