Teaching

Current Classes (Fall 2007)

Math Tutoring Lab

One of the best resources available to any students studying mathematics at UHH is our Math Tutoring Lab. Click here to go to its web page.

Archimedes Palimpsest

Here is an Archimedes palimpsest article.

Old Classes

Here you will be able to find webpages for classes I have taught in the past. This is a great resource as there are many exams with complete solutions!

Research

My area of expertise is Graph Theory.
I was trained as a Topological Graph Theorist; but, lately I have been doing Number Theoretical Graph Theory, in particular Super Edge-magic Labelings of Graphs with my good friends
Rikio Ichishima and Francesc Antoni Muntaner-Batle
(click here for a funny picture of the three of us and here to see a super edge-magic labeling of the Petersen graph). If you want to learn about graph labelings and how our research fits into this area look at the Dynamical Survey of Graph Labelings by Professor Joseph Gallian found in the Electronic Journal of Combinatorics. For a list of the published papers that I have co-authored look at my Curriculum Vitae.
