My name is Youchuan Zhang (she/her/hers) and I am a doctoral student in Human Development and Family Studies with a concentration in Lifespan Human Development and Family Diversity. My advisor is Dr. Yijie Wang. My research interests center on the psychological and physiological development of adolescents, particularly those experienced separation with parents due to parental migration for work. Currently, I am involved in multiple projects. The first project uses daily diary data on adolescents in rural China to investigate how parental migration impacts adolescent social experiences within different contexts (family, peer group, and school) and well-being in academic, psychosocial, and physiological domains. The second project uses meta-analytic techniques to investigate the extent to which protective factors of positive relationships in family, peer, school, and community settings are associated with the well-being of left-behind children and adolescents. The third project I am working on focuses on another marginalized adolescent population, particularly those from racial/ethnic minority background. This project follows 9th graders from diverse racial/ethnic groups in the U.S. through high school years and collects daily data annually to examine how peer ethnic/racial interactions influence adolescent cognitive, psychological, and physical well-being.
