This is a special encore edition of Under the Radar with Callie Crossley. This segment originally aired on October 15, 2017.

Intersectionality may be a buzz word in the news, personal essays and protest marches now, but it wasn’t a well-known concept until scholar Kimberlé Crenshaw developed and presented the theory in the 1980s. Crenshaw is a leading scholar in the fields of critical race theory and women’s studies, and a law professor at UCLA and Columbia University.

As a result of the excellence of her work, Crenshaw was awarded the 2017 Gittler Prize from Brandeis University, which is granted to scholars whose work makes a lasting contribution to racial, ethnic or religious relations. This is the latest of Crenshaw's awards and honors which include a fellowship at Stanford, two professor of the year awards at UCLA, a spot on Ebony's Power 100 and the number one spot on Ms. magazine's feminist heroes of 2015.

In our conversation 3 years ago Crenshaw explained her theory of intersectionality, and how has it evolved and grown outside of the scholastic world.
