Research Overview

I am interested in examining the inferences that people make about others’ goals and motivations within educational and social environments. My work focuses on competition, achievement motivation, income inequality, and research methodology. I am especially passionate about teaching statistical methods, including R, Bayesian data analysis, and simulation-based research design.
