 Immediate Past Chair: Huntington Potter, PhD

Dr. Potter is Professor of Neurology. Member of the Linda Crnic Center for Down Syndrome, and Director of the Rocky Mountain Alzheimer’s Disease Center at the University of Colorado Anschutz Medical Center. Previously, Dr. Potter studied, researched and taught for 30 years at Harvard University. He then designed and directed the Florida Alzheimer’s Disease Research Center and the Johnnie B. Byrd Sr. Alzheimer’s Center & Research Institute. Dr. Potter is credited with the first demonstration of the Holliday intermediate in genetic recombination, the perfection of electroporation for gene transfer, and the co-discovery of the essential role of inflammation and the amyloid-promoting activity of the apoE-4 protein in Alzheimer's disease. He also discovered that Alzheimer's disease and Down syndrome, which invariably leads to Alzheimer's by age 30-40, are mechanistically related to each other and to cancer through the development of cells with abnormal numbers of chromosomes. Recently, he and his colleagues have found such cell cycle defects in numerous other neurodegenerative diseases, providing a novel approach to diagnosis and therapy. They are also developing several new treatments for Alzheimer’s disease for testing first in animals and soon in humans. One, GM-CSF/Leukine, is currently in clinical trials. Dr. Potter is author of over 100 scientific articles, books and patents, has received numerous awards for his work, and is a Fellow of the American Association for the Advancement of Science and the National Academy of Inventors. His electron micrographs of DNA are on permanent exhibit in the National American History Museum of the Smithsonian Institute in Washington D.C.
