Erica Nicole Walker (born c. 1971) is an American mathematician and the Clifford Brewster Upton Professor of Mathematics Education at Teachers College, Columbia University, where she also serves as the Chairperson of the Department of Mathematics, Science, and Technology and as the Director of the Institute for Urban and Minority Education.
Walker’s research focuses on the "social and cultural factors as well as educational policies and practices that facilitate mathematics engagement, learning and performance, especially for underserved students".
After obtaining her graduate degree, Walker taught high school mathematics in Atlanta, Georgia.
Her teaching experience and earlier observation of few African-American students in upper level math courses during college led to an interest in and intent to encourage more African-American students to take advanced math classes, as well as to the conference of several teaching awards.
[7] Recognized by the National Association of Mathematicians and the Association for Women in Mathematics for her scholarship and practice, Walker collaborates with teachers, schools, districts, organizations, and media outlets to promote mathematics excellence and equity for young people.
