Dr. John Hyatt

Research Interests:

Dr. Hyatt conducts research into the chemistry of naturally occurring organic compounds having antioxidant activity. In particular, he is involved with isolation, purification, and structural modification of the rare members of the vitamin E family of compounds (tocols). He also does total synthesis of compounds in this class, and of unnatural analogs and homologs of natural antioxidants. In collaborations with biomedical researchers, the application of  these compounds to the management of chronic diseases such as diabetes and inflammatory bowel disease is under study. Dr. Hyatt also is active in research on the antiradiation activity of certain tocols.
