Q: Please list any teaching or speaking experience you have had, including subject matter:
A: While in an NIH postdoctal, I taught portions of toxicology courses to undergraduates at San Francisco State University, College of Marin College, and San Quentin State Prison (accredited by Sonoma State University). Also I taught toxicology to medical, dental, pharmacy, nursing and graduate students. At the University of Mississippi, as a tenured assistant professor of pharmacology and toxicology, I set up a doctoral program in toxicology with a core toxicology course curriculum. As a result of the six years I was there, 11 students received their PhD degrees. Also I taught an undergraduate course in forensic toxicology.

In industry, I was group leader in general toxicology for a group of 5 pharma related companies (Revlon Health Care Group) and, for 13 years, principal toxicologist (ARCO Chemical Company) responsible for FDA related projects. Both positions involved teaching and speaking experience.

As an example, I organized the workshop: Optimizing The Review Process of Food Additives and GRAS Petitions. This one-day workshop in Washington DC, was sponsored by the International Society of Regulatory Toxicology and Pharmacology. Two panels of FDA and Industry members (including myself) discussed potential solutions for the approval of macronutrient additives. I edited a series of papers from this workshop, published by the journal Regulatory Toxicology and Pharmacology.
