Overview


Humans are fundamentally social beings, and their interactions represent a core aspect of human nature. My research focuses on how individuals’ social identities and experiences across the lifespan motivate their social perceptions and behaviors particularly in diverse settings.

More specifically I am interested in three main questions:
1) how intergroup contact shapes interracial interaction outcomes for both racial majority and racial minority individuals
2) how having multiple racial or social identities more broadly affects various types of behavior including complex thinking, social behavior, and identity malleability
3) what contexts in particular may influence how people perceive or socially categorize each other across group boundaries

Therefore, the overall goal of my research program is to investigate the attitudinal and behavioral effects stemming from exposure to racial and gender diversity as a means to pinpoint pathways that one can utilize to foster more positive group relations for both adult and child populations. By exploring the developmental origins of social identity and intergroup perceptions we can pinpoint some of the antecedents that predict adult behavior in diverse settings.
