Areas of Research Interest:

Analysis, Algebra, Number Theory and Cryptography

My interests in pure mathematics are not focused on a particular area of research. I have many different interests and work on them as time and opportunity allow. I tend to write historically motivated general interest articles that might appeal to non-mathematicians, mathematics teachers and students or mathematicians from another area of specialization.

In the spring of 2003, I researched ideas related to the application of analysis and topology to fractals using the work of Michael Barnsley and Gerald Edgar and presented this research in a series of two one-hour lectures.

I have also researched the distribution of complex primes and the properties of the Gaussian integers as a Euclidean Ring. Using Gauss' work in Disquisitiones Arithmeticae , I wrote a paper tracing the arguments Gauss used in proving that what is today known as the multiplicative group Z( p )* is cyclic for all primes p. In addition, I completed a paper that is a historical consideration of the application of the ideas of Gauss and Euler by Whitfield Diffie and Martin Hellman to create the fundamentals of public-key cryptography.

I became interested in cryptography as a result of reading the first section of Prof. Neal Koblitz's book A Course in Number Theory and Cryptography . I researched the RSA Cryptosystem and Diffie-Hellman key exchange and the algebraic number theory that underlies these processes. I later used this research as a basis for a unit on modular arithmetic that I taught in the MAT 101 course at the University of Maine. A second unit for MAT 101 was based on number systems in bases other than 10. The students calculated in other bases using standard algorithms and considered the creation of fractions in base 12 (duodecimals). This activity was subsequently adapted by Professor John Donovan for a week of lessons for his MAT 400 course for teachers in which I participated as a teaching assistant.
