Winona Guo and Priya Vulchi are authors and activists who met in 2014 as high school sophomores in Princeton, New Jersey. Guo is Chinese American, and Vulchi is Indian American, exemplifying the role of women of color in social justice activism and education. Guo graduated from Harvard in 2022, and Vulchi graduated from Princeton in 2022.

Guo and Vulchi gave a TED Talk, “What It Takes to Be Racially Literate,” in 2018 and are the youngest TED Talk speakers. They have also spoken at TEDWomen, the United Nations’ Girl Up Conference, and various schools. Guo and Vulchi published a now out-of-print racial literacy textbook, The Classroom Index, during their junior year of high school. Jointly sponsored by the Princeton University Department of African American Studies and the Princeton Education Foundation, the book was meant for K-12 educators and contained stories from interviewees in the Northeast US, a racial literacy toolbox, and a reference guide. The book was aimed at educators wanting to add to their lesson plans and facilitate classroom discussions about race. Tell Me Who You Are: Sharing Our Stories of Race, Culture & Identity builds off The Classroom Index by adding stories from people across the US, as well as research, statistics, quotes, and definitions of terms and concepts.
