Skylar Wynn is a Senior Research Assistant at the Global Women’s Institute at the George Washington University. She received her bachelor’s degree with honors in Women's Studies from Old Dominion University in May 2015. As an undergraduate, Skylar interned with the Old Dominion University Women’s Center on campus focusing on empowerment, activism and creating a sexual assault free environment. She is passionate about exploring the politics of identity within girlhood in order to provide a counter-cultural experience for girls that promotes empowerment, inclusivity and global consciousness. 

During this time, she was the recipient of multiple honors such as the Anita Clair Fellman Service-Learning Scholarship, the Carolyn Rhodes Undergraduate Scholarship, Women's Studies Student of the Year Award and an International Research Award. After studying abroad in South Africa, Skylar created Project Annette to offer assistance to a secondary school she had spent time at while focusing on education and gender equality. In partnership with Education without Borders, they were able to fund two programs promoting early childhood literacy. Both programs have been proposed to continue in 2016. As Skylar completed her senior year at Old Dominion University, she was selected to be featured on the ODU main website as a commencement success story.
