Dr. Bergeron received his undergraduate degree from Clark University and his PhD in Organic Chemistry from Brandeis University. He studied under Nobel Laureate Konrad Bloch at Harvard and joined the chemistry faculty at the University of Maryland. In 1978, he moved to the University of Florida Department of Medicinal Chemistry where he established his expertise in polyamine and iron metabolism, leading to the development of anticancer drugs and treatments for children with iron overload disease. He has published 200 papers and a bioorganic chemistry text, edited two books and generated over 200 patents. Six of his discoveries have reached human clinical trials.
