Bruce N. Ames

Bruce Nathan Ames was an American biochemist who was a professor of biochemistry and Molecular Biology Emeritus at the University of California, Berkeley, and was a senior scientist at Children's Hospital Oakland Research Institute (CHORI). Ames made contributions to understanding the mechanisms of mutagenesis and DNA repair. He invented the Ames test, a widely used assay for easily and cheaply evaluating the mutagenicity of compounds. The test revolutionized the field of toxicology and has played a crucial role in identifying numerous environmental and industrial carcinogens.
