Research interests

Methodologically, my research interests include (1) continuous and categorical dynamic factor models and nonlinear time series models, (2) linear and nonlinear models for analyzing longitudinal data, (3) dynamical systems analysis, and (4) Bayesian methods and statistical computing. From a substantive perspective, I am interested in the analysis of intraindividual change and interindividual differences in change of life span development, cognitive aging, and emotion.
