MARIE DUNFORD, Ph.D., R.D., has been involved in sports nutrition since the mid-1980s. In 1985, while a faculty member at California State University, Fresno, she created the curriculum for an upper-division course entitled "Nutrition and the Athlete." She taught the course for a total of 16 years, during which time she interacted with thousands of student athletes. This direct exposure to nutrition and exercise science majors and NCAA Division I athletes helped her to develop an understanding of how students learn and the sports nutrition topics that are the most difficult for students to master. In addition to this textbook, Dr. Dunford has written three other books and numerous online sports nutrition courses for nutrition and exercise professionals. She is an active member of SCAN--the Sports, Cardiovascular, and Wellness Nutritionists--a dietetic practice group of the American Dietetic Association, and a member of the American College of Sports Medicine. She is an avid recreational tennis player and a struggling student of French.
