Amaya Mitchell, Graduate Student
Amaya Mitchell
Amaya Mitchell is a fourth-year doctoral student whose research examines how racial hierarchies and broader systems of oppression shape the dynamics of close relationships. Her work examines how racism and racialized stereotypes are reproduced in romantic partnerships through intergroup processes and person perception, all operating within enduring structures of power. Grounded in critical theories, her research explores the psychological mechanisms underlying phenomena like racialized attraction, romantic preferences, and the instrumentalization of people of color in relational life. She uses experimental, survey-based, and reflexive qualitative methods to inform theory and develop applied strategies for dismantling inequality in systems of social and emotional intimacy.

Prior to matriculating into graduate school, Daniel spent two transformative years as Dr. Sa-kiera Hudson’s inaugural lab manager at the University of California, Berkeley.

He received the National Science Foundation (NSF) Graduate Research Fellowship Program (GRFP) award (2024) for his project, Ambivalent stereotypes of Asian Americans and their hierarchy-enhancing function in US society.
