Research in my lab examines why systems of group-based social inequality are ubiquitous and resistant to change.  Our current research centers around three major themes:

1. why individuals who qualify equally for membership in more than one group (e.g., biracial people) are categorized and perceived as belonging more to their lower status parent group,
2. the nature of social dominance orientation (SDO), or individual differences in the preference for inequality between groups (e.g., race or caste groups), and
3. the endorsement of ideologies and beliefs that justify group-based inequality and discrimination (that is, beliefs that make inequality seem fair or legitimate).
