Suji Jung PhD

I am a highly self-motivated, independent, and productive researcher with professional research and field experience in child development. My research interests lie in child language and cognitive development, word/concept learning, self-directed learning, and parent-child interaction. My work integrates a range of theoretical approaches from developmental psychology, linguistics, and early childhood education.
