Peter C. Mayer followed his father to Caltech, graduating in physics. However, although he has used his natural science education in some of his work and is using it in his retirement, he never was a practicing physicist. He followed his father to grad school at the University of California at Berkeley, but earned his Ph.D. in a very different field, economics. He has served as an academic, government and utility economist in Ohio, Guam, Japan, and China. Like his father, his American directness has served him well. He is amusing himself in retirement by applying economic theory to problems in biology.
