Yoonyoung Kwak, Ph.D.

senior Data analyst


Dr. Yoonyoung Kwak graduated from Yonsei University in South Korea with her bachelor’s degree in Psychology. She also attended the University of California, Santa Barbara for a year through a study abroad program, which encouraged her to pursue advanced degrees in the United States later. After she earned a master’s degree in Child & Family Studies at Yonsei, she worked as a counselor and as a researcher for at-risk adolescents in particular. She, then, moved to the United States and pursued a Ph.D. in Human Development & Family Studies at Purdue University.

Her primary research interests include at-risk children and adolescents such as maltreated adolescents, sexually exploited children, minority adolescents, and runaway adolescents, and how they overcome their adversities. She has published articles in peer-reviewed journals such as Child Abuse & Neglect and American Journal of Orthopsychiatry.

She is also interested in advanced statistical analyses and methodologies. She earned an M.S. in Statistics as well while she was at Purdue. She has strong quantitative and qualitative analytic skills. She uses several statistical software programs including SAS, STATA, SPSS, R, and Mplus. As a certified programmer in SAS, she is an expert in data management and cleaning, especially for large and longitudinal data. The statistical analytic methods she has been using include structural equation modeling, multi-level mixed-effects generalized linear modeling, longitudinal growth curve modeling, latent class analysis, cross-lagged panel models, missing data analyses (e.g., multiple imputation and FIML) as well as any regression-based or ANOVA-based methods.
