Dr. Cordell obtained her undergraduate degree in Systems Science and Engineering at Washington University in St. Louis, a master's in Mathematics at St. Louis University, and a D.A. in Mathematics at the University of Illinois at Chicago. She is dedicated to supporting historically underrepresented students and diverse student populations in persisting and succeeding in mathematics and STEM fields through her teaching, research, and service.

Dr. Cordell teaches both pure mathematics and mathematics education courses at the undergraduate and graduate levels. Her research interests are in the area of mathematics education. Her research focuses on the identity development of underrepresented students in mathematics, relationships between marginalized students' identity development and participation in collaborative mathematics classrooms, and creating equitable mathematics learning environments for marginalized students.

Dr. Cordell has published her research in education and mathematics education journals, including the *Journal of Urban Learning, Teaching, and Research, *the *Mathematics Education Research Journal*, and the *Journal of Urban Mathematics Education*. She has also presented her research at local, national, and international conferences, including the National Council of Teachers of Mathematics, the annual meeting of the American Educational Research Association, and the Conference of the International Group for the Psychology of Mathematics Education.

Dr. Cordell has also worked collaboratively with undergraduate students, graduate students, and mathematics faculty on various research projects for two years, including Honors students and McNair students. Moreover, Dr. Cordell is the Faculty Coordinator of the Mathematics Enrichment Workshop Program (MEWP), the mathematics component of the EMERGE Summer Program, and the Mathematics Education Learning Community at NEIU. Dr. Cordell also serves on several committees including the Mathematics Development Curriculum Committee, the Undergraduate Program Committee (Mathematics), and the Title III Grant Program Advisory Group.
