Chrissy Trinter

Associate Professor, Mathematics Education


Chrissy Trinter is an Associate Professor of Mathematics Education, in the Center for STEM Education and a faculty member and Fellow of the Institute for Educational Initiatives at the University of Notre Dame. Her work centers on teacher development and her research interests include teacher leadership and curriculum studies in mathematics education. She is particularly interested in elements of curriculum and instruction that fall within the intersection of creativity and mathematics education.

Prior to joining the Center for STEM Education, she was a faculty member at Virginia Commonwealth University, where her courses included Curriculum Advanced Theory, Mathematics Teacher Leadership I, II, and III; Teaching Mathematics for Middle and Secondary Education; Research Proposal Writing, among others.

Dr. Trinter was a Research Scientist at the Curry School of Education, University of Virginia where she also earned her doctoral degree. During this time, she was the lead author on several award-winning curricular units. Prior, Dr. Trinter taught middle and high school mathematics in the northeast as well as overseas.
