# Cathy Kessel

Cathy Kessel is a U.S. researcher in mathematics education and consultant, past-president of Association for Women in Mathematics, winner of the Association for Women in Mathematics Louise Hay Award, and a blogger on Mathematics and Education. She served as an editor for Illustrative Mathematics from the end of 2015 through July 15, 2017.

## Biography

Kessel received her Ph.D. in mathematics from the University of Colorado Boulder, specializing in mathematical logic, and taught for three years after earning her Ph.D. She taught for a total of 13 years as a graduate and postgraduate until the 1990s when she made the switch to research in education. She began auditing courses and working on research projects at the School of Education at the University of California at Berkeley. This led to a career that included editing reports, books, articles, and curriculum and standards documents. She was the president of the Association for Women in Mathematics from 2007 to 2009 and worked as a mathematics education consultant through 2015 and again after she left Illustrative Mathematics in 2017.
