Microarray technology provides a way of studying which genes are active in different types of cell tissue, but analyzing the resulting data has many challenges. Unlike traditional statistics in which one has many more replicates than variables, in microarray data there are many more variables (the genes) than there are replicates (the chips or slides), so new statistical methods, or at least ways of pre-processing the data so that traditional means can be used, are needed. I am currently working on useful methods of preprocessing. This need to find ways of analyzing "small samples" (i.e., few replicates) also occurs in studies at the College of Veterinary Medicine, where I analyze data from experiments, often with small samples. So my work in each area compliments the other.
Another and original research hat is in the fields of Algebraic K-Theory and cyclic and Hochschild homologies, where my research has centered on determining the relationships between the K-theory and the homology theories and exploiting these relationships to provide algorthms for computing the K-theory and cyclic homology.
Lastly, I have interest in Mathematics Education, particularly at the post-seconday level. While I have published no research articles myself, I have been the Ph.D. advisor for two people with Mathematics Education speciality as well as helped design and then "ran", i.e., do the advising for, an MS in Mathematics program for people who want to teach at the secondary and post-secondary levels.

A Survey of Mathematical Problems - Fall 2006, Fall 2009, Fall 2010, and Fall 2013
A Survey of Mathematical Problems is a two semester, first year graduate,
course written for both people interested in teaching and people who
might need help transitioning to graduate work, e.g., because they didn't
have a full mathematics undergraduate major or not all subjects were
offered at their undergraduate school or have been away from school for a
while. We also suspect that the
course may work as a senior seminar course.
The following is the instructor's guide without the solutions to the
exercises and problems. We (Harold Boas and I) are interested
in how the course works for others. We give permission to copy the file
for classroom use as long as you don't make money off of the copies or
publish our work as yours. If you make money off of the copies, send us half.

The course is written to be done with the students working in groups.
Since we want area high school teachers to take the course, we offer it
once a week for three hours (Thursdays 6-9 pm). In 2004 the course was
taught twice a week for 1 1/4 hours each time, which was also fine,
but we do not recommend using
it in three 50 minute classes per week as the students need time to
mull over problems. In Fall 2006, 2009, 2010, and 2013, we offered Math 645 as a distance course. To read the
home page for the course, click here.
In Spring 2010 we offered Math 646 as a distance course. To read the home page for the course, click here.
Factoring polynomials with Rational Coefficients
Many courses, from college algebra to graduate algebra, teach or require the
knowledge of factoring polynomial with rational coefficients. Yet many of
the theorems and procedures I learned in high school aren't taught today.
The following link to a .pdf file (see below for a link to Acrobat Reader if
you need it) is a handout I constructed and have used with prospective teachers,undergradate majors, and graduate students. The handout contains all the proofs, which may be ignored by those interested only in the computational aspects. There are theorems that are unusual but useful in here as well. Factoring Theorems
The handout is copywrited but you have permission to reproduce it and recoup your costs, but you may not publish it as your own or make money on it. Should you make any profit, send me half :-)
Trying to Make the World a Better Place
Starting in January, 1990 and ending in July, 1994, the Mathematical
Association of America's Committee on the Participation of Women put on
skits at the Winter and Summer Joint Mathematics meetings. These skits are,
we hope, funny and enjoyable but also portray micro-inequities, those small,
usually humorous, injustices that often wear at women because they happen so
frequently. Unfortunately, almost all of them still occur, but perhaps not
as frequently. I hope you will enjoy them too. The following file of the
skits is a .pdf
