Lijuan Peggy Wang's research interests are in the areas of longitudinal data
analysis and mixed-effects modeling. She is also interested in psychological and educational measurement. Her current research project involves developing and applying models for multivariate nonnormal data such as longitudinal ceiling data and multivariate zero-inflated count data.
