- intergroup relations, prejudice, stereotyping, and discrimination

- personality and individual differences

- immigration and intergroup threat

- intergroup contact, intergroup friendships, and emotions (e.g., disgust, anxiety, empathy)

My primary research interests examine intergroup processes related to prejudice, stereotyping, and discrimination. This overall focus can be broken down into several key areas of investigation. First, how has contemporary prejudice transformed itself from overt and direct bias to more subtle and indicrect forms? How can these subtle biases be detected and combated among otherwise well-meaning individuals? Second, to what extent do personality constructs such as authoritarianism and social dominance predict and shape the expression of prejudice and discrimination? Third, how does the perception of intergroup threat posed by immigrants, refugees, and outgroups generally exacerbate negative intergroup outcomes? What social and personal factors trigger intergroup anxiety, and what are its consequences?

Most recently, my research addresses the contextual and personality factors involved in the attenuation of intergroup conflict, such as encouraging common ingroup categorization and identification. Specifically, I am testing the benefits of increasing positive intergroup contact and using intergroup friendships to reduce bias in a variety of settings.
