### 4.2 Thesis topics that I may supervise

My research area is quantitative psychology–the statistical modeling of psychological data. If you are planning to study quantitative psychology, I suggest you to learn R, an open source statistical environment. You may get familiar with the area of quantitative psychology by reading a few recent issues in the following journals.

- Behavior Research Methods
- British Journal of Mathematical and Statistical Psychology
- Educational and Psychological Measurement
- Journal of Educational and Behavioral Statistics
- Multivariate Behavioral Research
- Organizational Research Methods
- Psychological Methods
- Research Synthesis Methods
- Sociological Methodology
- Sociological Methods and Research
- Structural Equation Modeling: A Multidisciplinary Journal

I am interested in supervising topics in one of the followings areas.
