Dr. deLaubenfels' Résumé
How to Contact Us

Ralph deLaubenfels and Karen deLaubenfels formed Teacher-Scholar Institute in 2009. The designation "teacher-scholar" reflects the belief that teaching and research (in the subject matter being taught - not "education research") are symbiotic. This is particularly true in mathematics, since the primary purpose of mathematics research is expository: clarification, unification, and simplification.

Dr. and Mrs. deLaubenfels have home-schooled their three children K-12.
