about me

Welcome to my website

For the past three decades I have been involved in the design, development and testing of educational computer simulations and games. Most of my simulation games have been based on mathematical models developed elsewhere, mainly in research institutes. I have focused on making these validated and tested models available to education.

This website presents my career portfolio. I have described most of my software products, and a list of my publications is provided. In addition, I invite you to study my  free ebooks about the design, development and implementation of effective educational computer simulations. These ebooks are both research based and grounded in over 25 years of experience.
