Dr. Mulvey's research interests focus on social-cognitive development, in particular moral and social development. She conducts research examining theory of mind, social exclusion, and group dynamics, including when children challenge peer group norms. Her work focuses on intergroup contexts, and examines the influence of children's bias, prejudice and stereotypes on their intergroup relations. Her work also examines broadening the participation of underrepresented groups in the STEM fields and understanding stereotypes regarding who can and should be a scientist.
