Having graduated with a B.A. from Columbia University in the City of New York in Women, Gender, and Sexuality Studies and Psychology, Xaelah developed an early interest in and dedication to understanding modes of social difference and the resulting inequities tied to these various social positions. During her time as an undergraduate, she volunteered with Columbia’s PHE chapter as both a Health Educator and a two-year Leadership Council member, wherein she paid close attention to the use of language and its impacts on both her volunteers and the ninth graders in PHE’s program. In her roles as a facilitator for Columbia’s first-year identity awareness program, Under1Roof, and an executive board member for Proud Colors, a group for queer and trans students of color, she brought both a critical engagement to dialogue and a commitment to peer accountability to these spaces through centering notions of privilege, power, and oppression. She hopes to generate a similar commitment to these discussions of social difference within her New York program peers and college volunteers.
