Dr. Craig C. Mello is an investigator at the Howard Hughes Medical Institute, the Blais University Chair in Molecular Medicine and codirector of the RNA Therapeutics Institute at the University of Massachusetts Medical School. Dr. Mello's lab uses the nematode C. elegans as a model system to study embryogenesis and gene silencing. His collaborative work with Dr. Andrew Fire led to the discovery of RNA interference (RNAi), for which they shared the 2006 Nobel Prize in Physiology or Medicine. Together they showed that when C. elegans is exposed to double-stranded ribonucleic acid—dsRNA, a molecule that mimics a signature of viral infection—the worm mounts a sequence-specific silencing reaction that interferes with the expression of cognate cellular RNAs. For the layperson, RNAi is the cell's search engine; the Google of the cell. RNAi allows researchers to rapidly "knock out" the expression of specific genes and to thus define the biological functions of those genes. RNAi also provides a potential therapeutic avenue to silence genes that contribute to disease. Before the Nobel Prize, Dr. Mello's work on RNAi was recognized with several awards, including the National Academy of Sciences Molecular Biology Award, the Canadian Gairdner International Award, the Paul Ehrlich and Ludwig Darmstaedter Award and the Dr. Paul Janssen Award for Biomedical Research. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society.
