Prejudice, stereotyping, and discrimination often show different psychological patterns depending on which social group they are targeting. My research focuses on these differences, highlighting cases where addressing underexamined target groups reveals novel insights about bias that would otherwise have escaped notice.

Some of my work has focused on two specific kinds of stigmatized groups that pervade our social environment yet receive relatively little mainstream attention—intermediate social groups and people with concealable stigmatized identities.

Intermediate Social Groups

One of my major lines of research examines bias surrounding "intermediate" groups that are perceived to fall between more commonly recognized advantaged and disadvantaged groups, such as biracial and bisexual people.

Much intergroup research is built on groups that represent "endpoints" of a dimension of social identity, such as White, Black, heterosexual, and gay/lesbian people. Social groups who fall between these more readily recognized advantaged and disadvantaged groups (e.g., biracial people, bisexual people) have received less attention. My work demonstrates that considering intermediate groups yields results that could not have been predicted based on more traditionally studied groups alone. Specifically, intermediate groups are often perceived as less "real" than endpoint groups, and this realness helps to clarify cases where intermediate groups are evaluated negatively.

Concealable Stigmatized Identities

In work that sometimes overlaps with intermediate groups, I also examine perceptions of people with concealable stigmatized identities. These groups are sometimes overlooked because their members are not immediately identifiable. My research on bisexuality, an intermediate social identity that is frequently concealable, falls into this category. Some of my other research pertains to attitudes toward transgender people and people with stigmatized physical and mental health conditions like HIV and depression.


Several aspects of my research have applications in areas such as law, public health, and education. For example, I have an ongoing investigation of the expressive effects of law on attitudes toward social groups. Under some conditions, legal protection of a marginalized group may mitigate negative social attitudes toward that group. I have studied health consequences of stigma in the context of HIV and injection drug use. Finally, my research on racial and sexual orientation bias in the domain of medical training facilitates an understanding of both health disparities resulting from biased medical care and what works (and doesn't work) in anti-bias education.
