Profile Picture


I started teaching computer science at the University of Iowa when I was 25 years old. Over the years I have taught over 35 different classes. While I was still at the UI, I created a computer assisted instruction (CAI) authoring and delivery package that was deployed nation-wide in many of the largest K-12 schools in the country. To support the system, I created the first Apple-based networked instructional management system in the country. My software supported graphics, animation and audio at a time when multimedia was in its infancy. This experience instilled a life long passion for multimedia. I wrote my first video game in 1978.

I am the president of Argos Consulting, a private company that I started in 1979 to do computer software design and development. The company has done contract work for some of the country's largest corporations, including Microsoft, Albertsons, and Jewell/Osco as well as developing software to support research at Universities.

In the mid 80s I left teaching briefly to become the director of a Consortium that provided the computing resources for 3 Colleges (Coe, Cornell and Mount Mercy). This position convinced me that I didn't want to be an administrator, so I returned to my true love, teaching and I've been doing it ever since. In addition to computer science, I also have degrees in statistics, instructional design and administration.

In the last 10 years, I have developed an interest in international travel. I have taken study abroad groups to China, Japan, Germany, Greece, France, Ireland, Italy, Mexico, London and Oxford.
