Chrissy Trinter, Ph.D.

Director of CASTLE; Associate Professor, Mathematics Education; Faculty, ACE Teaching Fellows


Christine Trinter serves as an Associate Professor of Mathematics Education with the Alliance for Catholic Education and is the Director of the Catholic School Teacher Leadership Program. She teaches mathematics education courses in the Master of Education program, data visualization courses for the Education, Schooling and Society supplemental major and Computer Science minor, and a course focused on the mutuality of quantity and the Spirit to first year undergraduates. Trinter also supervises student teachers in the ACE Teaching Fellows program.

After earning her B.A. from Fordham University, Christine served in the Jesuit Volunteer Corps then taught in both Catholic and public middle and high schools in both Massachusetts and New York. She went on to earn an M.A. and a Ph.D. in mathematics education from Columbia University and the University of Virginia, respectively. 

Her research and scholarship focus on factors associated with teacher development, specifically related to teacher leadership and the integration of Catholic spirituality and mathematics education and the ways this integration  contributes to the flourishing of both teachers and students.

She and her husband, Phil, have three children, Gabrielle, Luke, and William.
