I've had three distinct careers: biomedical scientist; FDA drug regulator; and scholar at the Hoover Institution, a think-tank at Stanford University. During the first of these, I worked on various aspects of gene expression and regulation in viruses and mammalian cells. I was the co-discoverer of a critical enzyme in the influenza (flu) virus. While at the FDA, I was the medical reviewer for the first genetically engineered drugs and thus instrumental in the rapid licensing of human insulin and human growth hormone. Thereafter, I was a special assistant to the FDA commissioner and the founding director of the FDA's Office of Biotechnology. Since coming to the Hoover Institution, I have become well known for both contributions to peer-reviewed scholarly journals and for articles and books that make science, medicine, and technology accessible to non-experts. I have written four books and about 2,000 articles. I appear regularly on various nationally syndicated radio programs. My most frequent topics include genetic engineering, pharmaceutical development, and the debunking of various manifestions of junk science.
