Professor of Mathematics at Shippensburg University and Former Deputy Executive Director of the Mathematical Association of America
I have been a member of the Department of Mathematics at Shippensburg University since the fall of 1993. I hold a Ph.D. in Mathematics from Carnegie Mellon University, specializing in a branch of mathematical logic called model theory. 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.
While on a leave of absence from Ship from June 2016 to August 2018, I served as Deputy Executive Director of the Mathematical Association of America. In this position I worked on programs the MAA provides to members and the greater mathematics community, including MAA Sections, SIGMAAs, competitions, outreach, public policy, and professional development.

My involvement in the MAA has ranged from service to my regional MAA Section (EPADEL = Eastern PA & Delaware) in the form of organizing our Visiting Lecture program, coordinating our section NExT program, and serving as Secretary, Vice President, and President to involvement in the national organization as Visiting Mathematician, member of the Board of Governors (representing EPADEL), Second Vice President, and on staff as Deputy Executive Director from June 2016 to August 2018. I continue to be involved with MAA projects, included the MAA Instructional Practices Guide, the MAA META Math project, and the MAA CoMInDS project.
I have written (with Winston Crawley) a textbook for Discrete Mathematics published by John Wiley & Sons, Inc. Complete information about the book can be found at the Wiley website or on amazon.com. I have also created computer-based material 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 a MAA PREP workshop in summer of 2006 on teaching discrete mathematics.
From 2005 to 2016 I was involved in a joint project with Barbara Kaskosz of the University of Rhode Island involving the development of tutorials and workshops for training teaching and curriculum professionals in developing teaching and learning material using Adobe Flash. The central component of this work, the website www.flashandmath.com, is no longer maintained. This project was also supported by an NSF DUE grant (0535327), and it resulted in MAA PREP workshops during the summers of 2007 and 2008. As part of the project, Barbara and I wrote a book (Flash and Math Applets: Learn by Example) to help math and science instructors get started with Flash programming to create educational materia.
The FlashandMath project was honored with the 2009 ICTCM Award for Excellence and Innovation with the Use of Technology in Collegiate Mathematics. My current work is repurposing many of these ideas for mobile-friendly browsers using HTML5 Canvas.
