Dr. Yasmiyn Irizarry (she/her) is an Associate Professor of African and African Diaspora Studies at The University of Texas at Austin and founding director of the Numbers 4 Justice Lab at the Institute for Urban Policy Research & Analysis. Dr. Irizarry is a quantitative sociologist, race scholar, and survey methodologist. As a leading expert in the emerging field of QuantCrit, her research focuses on the critical study of race and racism within four overlapping areas of inquiry: (1) K-16 schooling contexts; (2) categorization, identity, and ascription, (3) social attitudes, prejudice, and discrimination; and (4) justice, marginalization, and social control. Much of this work considers the complex landscape of race, ethnicity, immigration, class, and place as intersecting identities, experiences, and interactions linked to systems of power.

Dr. Irizarry earned her BA from The Ohio State University and an MA and PhD in Sociology from Indiana University.
