I have directed four doctoral dissertations in combinatorial mathematics (Paul Becker, CMU 2000, Omar AbuGhneim, CMU 2005, Solomon Osifodunrin, CMU 2008, Jordan Webster, CMU 2009.

I have taught geometry and precalculus in CAMP (for gifted and talented high school students.)  I created and taught an introductory statistics class on the internet (1995.)

I created (with Arnold Hammel, CMU) MTH 522, The Mathematics of Cryptology.

  I created (with Doug Lapp, CMU) MTH 261, Problem-based Algebra and Calculus for Secondary Teachers.

I have directed approximately a dozen masters theses and Plan B papers. 

I have directed a variety of undergraduate students on projects in matrix analysis, graph theory and algebraic combinatorics, working with over thirty students in the last ten years.
