Dr. Ge (Gabriella) Jiang is an assistant professor in the Department of Educational Psychology at the University of Illinois at Urbana-Champaign. Dr. Jiang's research centers around two areas: (1) structural equation modeling (SEM) and (2) statistical learning. In the area of SEM, she studies test statistics, fit indices, robust estimation methods, measurement invariance, and equivalence testing. In the area of statistical learning, she studies regularization methods (lasso, ridge, elastic net) in the contexts of clustering. Substantively, she is interested in developing software packages to facilitate the use of quantitative methods and applying them to educational and psychological research.
