My undergraduate studies were in Applied Mathematics at Brown University in Providence, Rhode Island where I graduated with an Sc.B. in 1964. The next few years were spent at Rutgers: The State University of New Jersey with an M.S. completed in 1966 and a Ph.D. in 1970, both in Mathematics. Since that time I have been on the faculty at TCU.
In the 1980's my interests changed some. I began working on a degree in computer science finishing with a B.S. in 1987. (A new degree every 20 years or so, is a good thing!)


Variety being the "spice of life", I have tried to teach many different subject areas in mathematics. Currently I often teach Discrete Mathematics, Probability and Statistics, and Calculus. In past years I have had the good fortune to teach courses in the computer science department.

The cartoon by Aaron Brown is a caricature of what he dreamed happened in one of my Discrete Mathematics classes. You will get a hint of some of the good topics we discuss in that class. Click on the cartoon to see it life size.

Other Interests

Away from mathematics scuba diving is my favorite activity. It seems sometimes that the garden of Eden must have been underwater... coral reefs rank highly among the most beautiful places I have ever seen.

This picture of a "baby" elephant seal weighing approximately 500-1000 pounds, was taken at Los Islotes, a large rock formation in the Sea of Cortez near Lapaz, Mexico a few years ago. It's the closest I have ever been to a wild animal... he liked being petted. He playfully bit my head, and later my arm... he needs a dentist. I have pictures to prove it.!


Graduate school studies centered on General Topology with a particular interest in spaces of mappings of various types. Later when I was fortunate enough to have students of my own, we branched out into other areas. My first student Dr. John Gresham studied problems in dimension theory and the theory of retracts. Later, Dr. Mary P. Reagor made contributions in fuzzy topology, a new area at the time.
