My primary research interests lie at the intersection of moral judgment and social identity. Specifically, I focus on how group identities are formed based on moral judgments, and additionally how these identities enable perceptions of threat, outgroup essentialism, and derogation. I also have conducted research on the factors that influence stereotyping, prejudice, and discrimination based on racial and ethnic identity. Understanding cognitive and motivational factors that increase bias as well as testing interventions that decrease bias are key goals of this work.
My secondary interests relate to quantitative methodology and data analysis in psychological research. Recently many psychologists have questioned the replicability of psychological research. I believe better practices in the way we analyze our data can improve the reputation of psychology through ensuring we make proper conclusions based on our data. In this area of scholarship, I advocate against the use of statistical tests which are unnecessary or which inhibit the advancement of social psychological theory (i.e., variable centering in OLS regression, mediated moderation tests).
