            <p>Ingolf Ståhl is professor emeritus of the Stockholm School of Economics, a business school and private university in Stockholm, Sweden. Ståhl began teaching computer simulation in 1976. Since then, he has instructed over 7,000 university and advanced high school students at universities in Sweden, Norway, Germany, Latvia, and the United States. Ståhl's courses feature General Purpose Simulation Systems (GPSS) language. In collaboration with Henry Herper and Richard G. Born, Ståhl developed simulation software and instructional materials for micro-GPSS and WebGPSS. Ståhl is also noted for his groundbreaking work with Jesse H. Ausubel at the International Institute of Applied Systems Analysis in Laxenburg, Austria. In 1981, the two researchers introduced the concept of greenhouse gas emission trading, using simulation gaming to estimate carbon dioxide output. Ståhl has served as a banking and industry consultant in Sweden and is a frequent speaker at computer simulation conferences in Europe and the United States.</p>
