My methodological interests have evolved along four inter-related lines:
(1) Bayesian methods and statistical computing;
(2) longitudinal data analysis and time series analysis;
(3) structure equation modleing;
(4) study design and sample size determination.
I also work on developing new meta-analysis and machine learning techniques. From a substantive perspective, I am interested in applying quantitative methods in developmental, clinical, cognitive, educational, and health research.
I am currently recruiting potential graduate students.
