Research and Teaching Interests

Dr. Johnson's scholarship encompasses faculty professional development in STEM, commutative algebra, and the scholarship of teaching and learning in mathematics. Some of his projects with students have included: zero-divisor graphs of graded rings, hyperbolic geometry, and jigsaw sudoku puzzles. His main teaching interests lie in Abstract Algebra at the undergraduate (MAS 4301 & 4302) and graduate levels (MAS 5311 & 5312) and teaching mathematics to non-STEM majors (MGF 1106 & 1107) using active learning pedagogies.
