Summary Statement of Research Interests

  • My research interests in social psychology focus on persuasion and social influence, particularly how individuals' ideological beliefs and interpretations of social issues interact to affect their attitudes and behaviors.

    In quantitative psychology, I am interested in applying structural models of growth and change to longitudinal data, implementing and investigating the performance of Exploratory Data Mining techniques with particular interest in CART and Structural Equation Model Trees, and investigating and improving the robustness of meta-analysis to violations of common assumptions.

Research Specialties

  • Social influence: social norms, message construal. Structural analysis of longitudinal and cross-sectional data. Exploratory data mining. Meta analysis.
