I received my PhD in 1990 from the University of Pennsylvania’s Wharton School. I have been on the faculty here since then. My interests include business forecasting, objective setting in organizations, multimedia, and design.

Before starting my PhD I worked mainly in entrepreneurial ventures. My first job out of college was as an analyst for the Metropolitan Area Religious Coalition of Cincinnati, a public policy think tank, where I worked with church and civic leaders primarily to influence telecommunications and health policy. I was one of five during the earliest days of Thiel Audio, which has since become a leading manufacturer of high-end loudspeakers. In 1979, I founded Conceptual Instruments to develop The Desk Organizer. It created a new product category when it was published by Warner Software.

I have also worked at, and consulted with, some of the largest companies in the world, the federal government, and many universities, local governments, and non-profit organizations.

In 1998-99, I was a visiting scientist at IBM's Thomas J. Watson Research Laboratory, where I worked with the Computer Music Center on the design of interfaces for controlling sound and graphics in real-time. And last year, I was a visitor at Cornell’s Human Comuter Interaction lab.
