My research investigates how people perceive and respond to social inequity, with a particular focus on allyship and privilege. Integrating social psychology, organizational behavior, and cross-cultural research, I examine the emotional and cognitive processes that shape individuals’ willingness to challenge injustice, their interpretations of social privileges, and the dynamics of identity and power in workplace and societal contexts.

In my main line of work, I study how people leverage their own power and privilege to increase social equity in their organizations. I do this by examining the antecedents and consequences of allyship, the efforts of those who actively work for equity for marginalized groups, not as a member of that group but in solidarity with its struggle. I explore how emotions and cognitions shape ally behavior in organizations

In another line of work, I identify ongoing identity-based experiences that contribute to social inequality, such as objectification or bias. Importantly, I focus on ways organizations and managers can avoid these and instead create a more inclusive, equitable climate.

In a supplemental line of work, I look at how people judge norm violations, sanctions, and changing social norms across cultures. This fits in with my broader interest in the prevalence and enforcement of dominant social myths that perpetuate inequities.
