BSEE (Electrical Engineering) from Bradley University
Some graduate work in math at Ball State University
M.S. in Math from UIC

As an undergraduate I was interested in Communication Theory and Digital Signal Processing.  As a graduate student, I was most interested in Topology and Algebra with some leanings to Logic (Universal Algebra).
But these days, I really like to read books about the History of Mathematics.

Personally, I'm an avid fan of music.  I like to play music myself (guitar mostly) as well as have a relatively large collection of cds and mp3s.
