Alfred "Roc" Ordman
Biochemistry Program
Professor of Chemistry and Biochemistry, Beloit College
Visiting Professor of Biochemistry, Rush Medical College
Author: Nutrition Investigator

Email Address:

At Beloit since 1977

PERSONAL: Roc Ordman is married to the former Dance Instructor at Beloit, Eliza Freeman and has six children (two married, three graduated from college all in the summer of 2000). He has taught many different courses, from General Biology to Physiology to "What are the rules of the game of life?" to Organic Chemistry to Science Policy. He has traveled throughout the United States and 22 foreign countries, has worked in academia at institutions like Tel Aviv University in Israel, in industry at companies like Ciba-Geigy in Basel, Switzerland, in the military as a Preventive Medical Officer while serving in the Gulf War in Saudi Arabia, and in medical institutions like Rush Medical College. He was a Kellogg National Fellow, one of 50 people in the nation selected as future leaders of America. And he loves to sing.

ACADEMIC CONNECTIONS: His classes like to sing too. The Biochemistry Program of Beloit College

Roc's view of education 2010 - utube produced by Beloit student


Currently Roc is involved in research on obesity, vitamin C and its effect on cataracts and on brain trauma, and working on a popular nutrition book. In the spring of 2007, he conducted a clinical trial on a nutrient signaling formulation that led to weight loss in many of the 59 participants in the study. Given all the progress in nutrition research, how do we inform people about intelligent nutrition? See USA Today, page 1, October 22, 1994 .Recent publications include:

Current Research Interests (in which students are involved):

1. Informing the public about intelligent nutrition - see recent book by Walter Willett, head of School of Public Health, Harvard University.

2. Mechanism of aging - especially antioxidant vitamins A, C, E. This research involves determining appropriate dosages of antioxidant vitamins and water-soluble minerals for the human diet .

3. The biochemistry of youthful exuberance. Now that we are close to unraveling how to extend human life indefinitely, we need to understand what makes people want to stay alive and enjoy life. For lack of a formal term, I call it youthful exuberance. Young people want to be alive. But as people age, many lose that desire. What does that mean biochemically?
