Dr. Ryan P. Bowles is an expert in Rasch measurement, Item Response Theory, and Structural Equation Modeling with categorical outcomes. His research focuses on the assessment of early childhood language and literacy development. Dr. Bowles teaches Quantitative Research Methods, Applied Multivariate Data Analysis, Applied SEM, Longitudinal SEM, and Measurement.
Dr. Ahnalee Brincks specializes in latent variable modeling and has expertise in longitudinal data analysis, hierarchical linear models, structural equation modeling, and the analysis of data from randomized clinical trials.
Dr. Megan Maas specializes in latent class methodologies, longitudinal survey research, and dyadic data analysis to understand sexual behaviors, how online and offline sexual behaviors change over time, and how partners in intimate relationships affect one another. Dr. Maas teaches Research Design and Measurement and Quantitative Research Methods.
Dr. Amy K. Nuttall is an expert in structural equation modeling (SEM), longitudinal data analysis (LSEM), and mixture modeling. She employs these methods in longitudinal data (including intensive longitudinal “diary” sampling), family/dyadic data, and biological data to understand the impact of family processes and dynamics on development over time. Dr. Nuttall teaches Applied Multivariate Data Analysis, Applied SEM, and Longitudinal SEM.
Dr. Yijie Wang’s research employs experience sampling and longitudinal designs to understand development in daily lives and over time. Her work also uses secondary data from nationally representative samples such as the National Longitudinal Study of Adolescent to Adult Health (Add Health) and the Early Childhood Longitudinal Study (ECLS). Dr. Wang teaches Applied Multivariate Data Analysis.
