Inspired by the national protests for racial justice in the summer of 2020, the triennial MRJ explores the role mathematics plays in today’s movement for racial justice by convening mathematicians, statisticians, computer scientists, STEM educators, and members of the public interested in using the tools of these disciplines, to critically examine and eradicate racial disparities in society. MRJ will provide on-ramps for faculty and students interested in this work by creating a platform to discover the latest research on mathematics and racial justice, and opportunities to network and form collaborations with scholars at the forefront of these issues.
