Lijuan "Peggy" Wang
Assistant Professor
Ph.D., University of Virginia
Profile
Lijuan Wang's research interests are in the areas of longitudinal data analysis, multilevel modeling, and structural equation modeling. She is also interested in psychological and educational measurement. Her current research projects involve developing and applying models for analyzing multivariate nonnormal data such as censored data and zero-inflated count data. Substantively, she is interested in applying quantitative methods in cognitive aging and health research.
