I started teaching mathematics at College of DuPage in 2002. As an adjunct instructor, the classes I have taught include geometry, logic and set theory, graph theory, probability, statistics, algebra, and pre-calculus. I recently taught a workshop about how to use the equation editor to add math equations and symbols to tests and class presentations. In the past I coached a home-schooled (high school age) math team called Cornerstone. In recent years they have been Illinois state champions.
In 2007 I started working at FreshLook Marketing , a small company that does informational studies involving perishable foods. I do development for statistical modeling of products and also for store level reporting. The SAS language is used for programming/statistics and some visual basic (VBA) is used for constructing the spreadsheets delivered to clients.
Until 2001 I worked at Lucent Technologies (formerly Bell Laboratories, now Alcatel-Lucent). I worked in development, testing, and automated testing. I also worked with the Tools Information Group (TIG). We wrote tips about tools, programming languages, Sun workstations, the world-wide web, and other computer-related subjects.
One of my greatest interests is running. I used to run on the paths at lunch time when I worked at Lucent and I continue to run during lunchtime at FreshLook. In 2006 I joined the Glen Ellyn Runners group. I have run in 9 marathons - 6 at Chicago, 2 at Boston, and 1 at Milwaukee.
I like to play chess with my sons. Andrew is rated over 2000 which is much higher than me. I have been playing occasionally along with him at the adult chess tournaments but have given up hope of keeping up with him. Mark is rated over 1200 and he gives me quite a battle.
Toastmasters is a club that focuses on improving public speaking skills. I was a member of Toastmasters International for 13 years.
I have been a science fiction fan all of my life. I especially like Star Trek, Doctor Who, Hitchhikers Guide to the Galaxy, and Babylon 5. Although never going to a Star Trek convention, I did attend a Doctor Who convention back in the early 80's and saw Tom Baker in person. He's the one with the curly hair and long scarf who's always offering people "jelly babies". You may want to find out about Doctor Who by clicking on this link.
I graduated with an M.S. in Applied Math from the Math department at Michigan State University. As an undergraduate at MSU, I was a member of Lyman Briggs College and a member of the MSU Honors College. My wife also went to MSU and we met while I was working in Lansing and she was going to school. She didn't want to go out with me at first because I was a "math major" and she had visions of someone with a calculator on his belt. I assured her I never wore a calculator on my belt. The part about calculators not being invented yet back when I went to school was conveniently left out. We got married and moved to Illinois. We have four children - two going to college and two still at home.
