Steve Keeler is manager of the Geometry and Optimization group in Boeing's Applied Mathematics organization. The group specializes in geometric modeling, computer-aided geometric design, numerical optimization, multidisciplinary design optimization, data fitting and optimal control. They work with engineers on the design and manufacture of commercial aircraft, military and space systems. They also conduct research and development and do consulting and software development for non-Boeing customers. In the course of a year they may work on 100 different applications of mathematics. Steve joined Boeing after completing his doctorate in math at the University of Washington. Boeing's Applied Mathematics group works with engineers on the design and manufacture of Boeing products, conducts applied research and development, and does consulting and software development for non-Boeing customers. This talk is about the types of problems and applications we deal with and the mathematical disciplines and other skills which are important. It's also about why it's fun to do industrial applied math, how the personal rewards are different from those in academic research, and how we handle the occasional exasperations of corporate life. There are some suggestions for a mathematician contemplating an industrial career.
