DiAngelo (born September 8, 1956) is an American academic, lecturer, and author working in the fields of critical discourse analysis and whiteness studies.
She formerly served as a tenured professor of multicultural education at Westfield State University.
She is known for her work pertaining to white fragility, a term which she coined in 2011.
Born to a European American family, DiAngelo received a PhD in multicultural education from the University of Washington in 2004; her thesis constituted a discourse analysis of whiteness.
Becoming a professional academic, she taught at Westfield State University, where she became a tenured professor.
In a 2011 academic paper she put forward the concept of white fragility, the notion that white people become defensive when confronted with "racial stress".
She further promoted the idea through her 2018 book White Fragility.
