Local Organizers

The 2022 G2 Math Program would not have been possible without the efforts of CMU's Office of Diversity, Equity, and Inclusion, and in particular the wonderful team consisting of:

  • Michael Young (Associate Dean)

  • Cassandra Rios (Student Program Coordinator)

  • Demetrius Baldwin (Faculty/Staff Outreach)
