Associate Directors


Amanda Harrist, Ph.D.Amanda Harrist, Ph.D.

Professor, Bryan Close Chair in Early Childhood Development

Department: Human Development & Family Science

Office: 244 Human Sciences

Phone: 405-763-6811


Areas of Expertise: Parent-child and peer relations in development of child social competence; Psychosocial contexts of child obesity; theories of family resilience

Population of Interest: Rural school children; Pre-school and school-age children, their parents and siblings; Native-American school children.

Amanda Harrist received her B.A. in Plan II/Liberal Arts Honors at the University of Texas in 1984. She completed her Ph.D. at University of Tennessee in 1991, working as a Research Associate for the Child Development Project at UT Knoxville and Vanderbilt University. She joined the OSU faculty in 1998. Dr. Harrist’s research centers on an interest in the development of children’s social competence, specifically the early social antecedents of children’s competence and maladjustment exhibited in preschool and the early years of school, and the role social-cognition plays as a mediator.  To this end, she has explored the relation of children’s behavior in the peer group to early family (e.g., marriage, parent-child, sibling) interactions, observed both naturalistically and in the laboratory.  She is interested in interventions for children at risk in early social settings, and has pursued this via several funded projects, most recently in the USDA-funded Families & Schools for Health (FiSH) Project, a longitudinal study of the family and rural school contexts of child obesity. She also is working with OSU colleagues Dr. Carolyn Henry and Amanda Morris to refine a theory of family resilience.

Her current research includes an NIH-funded longitudinal study of women from pregnancy through two years after childbirth to examine the biopsychosocial impacts of maternal childhood adversity on adverse birth outcomes and early child development.

Ron Cox completed his B.A. in Psychology at Harding University, his M.A. in Marriage and Family Therapy at University of Louisiana, Monroe, and his Ph.D. in Human Ecology (with a minor in Methods of Quantitative Measurement) at Michigan State University in 2007. He joined OSU as a member of the faculty in 2007. Trained as a clinician in communication and systems theory, Dr. Cox draws on his clinical experience and quantitative expertise to translate research findings into interventions that are implemented in the community and evaluated. He then uses the information gleaned from these interventions to further inform his research. Dr. Cox’s primary work is currently funded by grants from the USDA, the NIH, the OSU Office of the Vice President for Research, the George Kaiser Family Foundation, and the Zarrow Foundation and focuses on developing and testing strategies that promote resilience among Latino immigrant youth and their families in a program called ¡Unidos Se Puede! He also leads the state-wide dissemination of an intervention designed to reduce trauma and foster resilience among children of divorcing parents titled, Co-Parenting for Resilience. Before returning to complete his Ph.D., Dr. Cox spent over 15 years residing in Venezuela, South America. This bi-cultural aspect of his personal and professional development informs much of his work as a scholar.
