Bio

Dr. Karen Hollebrands is the Associate Dean for Research and Innovation in the College of Education. She joined NC State in 2001 as an assistant professor of mathematics education and became a full professor in 2014. She was inducted into the Academy of Outstanding Teachers at NC State in 2009, was named an Alumni Distinguished Undergraduate Professor in 2014 and a University Faculty Scholar in 2015. She has served in various leadership roles for the National Council of Teachers of Mathematics (NCTM), the Association of Mathematics Teacher Educators (AMTE), and the North America Chapter of the International Group for the Psychology of Mathematics Education and AERA’s Special Interest Group for Research in Mathematics Education. She served as the Editor of the Mathematics Teacher Educator journal co-published by AMTE and NCTM from 2018-2022.

Dr. Hollebrands’ research examines the mathematical understandings students and teachers develop when using technology. Since 2001, she has partnered with faculty in the college and researchers at the Friday Institute to secure more than $10 million dollars to support her work on several different research projects including the Preparing to Teach Mathematics with Technology project, MOOCs for Educators, and four Noyce scholar programs. The technology-based curricula materials she has co-designed and studied have been implemented nationally and internationally. Most recently, as Associate Dean for Research, she supported faculty and researchers in the college to achieve an all-time record of receiving more the $42 million dollars during fiscal year 2023.
