This is a list of forty-odd projects I have done from my doctoral dissertation to my latest mathematically sophisticated tools in retail-based airline booking simulation. The early cellular projects reshaped the wireless telephone industry, many of these have made significant financial impact, and some are still earning tens of millions of dollars per year.
