My current mathematics research spans many areas of discrete mathematics including logic, combinatorics and graph theory. My educational agenda focuses on building skills in problem-solving, independent thinking, and communication, especially as these skills relate to the understanding of 'abstract' mathematics and the notion of mathematical proof.

For many years I was the Editor for the Loci Resources section of the a project of the for which I still serve on the Advisory Board. Most recently I have been involved with the Advisory Committee for the 2010 Mathematics Awareness Month with theme,. My other involvement in the MAA has ranged from service to my regional MAA Section in the form of organizing our Visiting Lecture program, coordinating our section NExT program, and serving as Vice President and then President to involvement in the national organization as Visiting Mathematician, member of the Board of Governors (representing EPADEL), and most recently Second Vice President. I am a member of the inaugural class of Project NExT, a wildly successful professional development program for new professors run by the MAA since 1994. I have written (with ) a textbook for Discrete Mathematics published by John Wiley & Sons, Inc. Complete information about the book can be found at the or on.

I have also created for teaching and learning mathematical reasoning and proof through an NSF DUE Educational Materials Development grant (0230755). This material supplements the discrete mathematics textbook. In addition, I ran an MAA on discrete mathematics during the summer of 2006. Since 2005 I have been involved in a joint project with of the University of Rhode Island that involves the development of tutorials and workshops for training teaching and curriculum professionals in developing teaching and learning material using. The central components of this project are the and the website.

This project is also supported by an NSF DUE grant (0535327), and it has also resulted in a during the summer of 2007 and another in planning for the summer of 2008. As part of the project, Barbara and I have written a book to help math and science instructors get started with Flash programming to create educational material. The FlashandMath project was honored with the 2009 ICTCM Award for Excellence and Innovation with the Use of Technology in Collegiate Mathematics. To see some of my other recent experiments with Flash,.

Did you know that games and puzzles have given birth to many of today's deepest mathematical subjects? Now, with Douglas Ensley and Winston Crawley's Introduction to Discrete Mathematics, you can explore mathematical writing, abstract structures, counting, discrete probability, and graph theory, through games, puzzles, patterns, magic tricks, and real-world problems. You will discover how new mathematical topics can be applied to everyday situations, learn how to work with proofs, and develop your problem-solving skills along the way. Online applications help improve your mathematical reasoning. Highly intriguing, interactive Flash-based applications illustrate key mathematical concepts and help you develop your ability to reason mathematically, solve problems, and work with proofs.
