Welcome! I am an assistant professor of Quantitative Methodology at the University of Georgia. A few things about me are as follows.
Research Interests
My research interests center on the optimal design of experimental studies, statistical power, replication and meta-analysis, multilevel moderation/mediation modeling, structural equation modeling, latent variable modeling, and their application in education, psychology, and health. I am also interested in sensitivity analysis, artificial intelligence, machine learning, computational and optimization methods, causal inference, categorical data analysis, quantitative policy research, prevention science, education equity, and school psychology issues.
