After 3 years at UC San Diego School of Medicine in the 1970s, I left to devote myself to a career in applied nutrition. I have been Research Director of several nutraceutical companies, as well as founding partner, President, and Science Director of a small nutraceutical company, NutriGuard Research. I have published about 300 technical papers in the biomedical literature, and have been a fervent advocate of whole-food plant-based diets and rational nutraceutical supplementation. In college, I was Editorial Director of UCSD's student newspaper, and I have maintained a lively interest in progressive politics over the years.
