Postdocs and Data Scientists

Ashley received her Ph.D. in Developmental Psychology from Yale University, where she worked with Drs. Yarrow Dunham and Karen Wynn assessing social cognition in infancy and early childhood. Her work looks at the mechanisms that underlie our emerging evaluations of social life with a particular emphasis on how messages about similarity guide children’s social preferences and inform their inferences about the structure of social groups. She is excited to apply these ideas to the study of gender development among, and prejudice toward, gender non-conforming youth.
