Dr. Lieny Jeon is an Assistant Professor in School of Education at Johns Hopkins University. She holds a B.A. in Child Welfare Studies from Sookmyung Women's University in South Korea and M.S. and Ph.D. degrees in Human Development and Family Science from The Ohio State University. Dr. Jeon’s research focuses upon the environmental factors, such as early childhood education, family characteristics, and neighborhood disadvantage that impact children’s lives. She is passionate about early childhood teachers’ social and emotional wellbeing and the way this impacts young children’s development; a great deal of her research interest focuses upon the associations between teachers’ social-emotional capacity (e.g., depression, stress, efficacy, motivation, commitment, etc.) and children’s social and emotional learning. She also examines how early childhood education buffers challenging home and neighborhood environments and maximizes at-risk children’s cognitive and social-emotional development.
