A Singaporean, she received her BSocSci from National University of Singapore, MA from Nanyang Technological University, and MA and PhD from University of Illinois. During her graduate studies, she won the Marion Morse Wood Research Fellowship, and was on the “List of teachers ranked as excellent by their students”. Her work with mentor Dr. Renée Baillargeon and other colleagues has been published recently in journals such as Proceedings of the National Academy of Sciences, USA, and in book chapters such as The Cognitive Neurosciences, APA Handbook of Personality and Social psychology, and Navigating the social world: What infants, children, and other species can teach us.
Research Interests
I am interested in how infants and toddlers make sense of the world around them, and what explanatory frameworks and learning mechanisms enable them to do so. My research explores early conceptual development in three core domains: biological, psychological, and sociomoral reasoning. In my research on biological reasoning, I examine what infants know about animals and the generalizations infants will make about animal kinds. My research on psychological reasoning examines toddlers’ false-belief reasoning ability. Currently, my research focuses on sociomoral reasoning, which examines infants and toddler’s expectations about interactions within and between groups.

My lab is recruiting! I am looking for enthusiastic undergraduate, postgraduate, and postdocs to join us. Please send enquiries to
