After spending time as a postdoctoral fellow in the laboratory of Dr. Edward Masoro, Dr. Lewis spent one year as a lecturer/researcher in the Department of Physiology at The University of Texas Health Science Center in San Antonio, TX. Dr. Lewis taught several recitation sections for Medical students in medical physiology. Dr. Lewis started his career as a Research Scientist at the Southwest Foundation for Biomedical Research in San Antonio Texas. At the Foundation Dr. Lewis focused on developing nonhuman primate animals as models for humans to study the effect of early nutrition on the development of chronic disease. This work focused on infant nutrition and fat cell development and cholesterol metabolism. After 12 years as a biomedical researcher he moved to Iowa State University to continue his research interests and to teach. At Iowa State University Dr. Lewis developed an interest in education and functional foods as approaches to prevent the development of chronic disease by lowering risks factors in young adults. Dr. Lewis accepted the challenge of becoming Department Chair at Cal Poly and started his tenure at Cal Poly on January 1, 2002. Dr. Lewis is continuing his research interests and enjoys teaching as well as leading a vibrant enthusiastic faculty in educating tomorrows nutritionist and food scientists.
