Craig MELLO, PhD

Professor, University of Massachusetts
Howard Hughes Medical Institute, USA
Nobel Prize in Physiology or Medicine (2006)

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. Using readily produced short synthetic dsRNAs, researchers can now silence any gene inorganisms as diverse as rice and humans. RNAi allows researchers to rapidly “knock out” the expression of specific genes and, thus, to define thebiological functions of those genes. RNAi also provides a potential therapeutic avenue to silence genes that cause or contribute to diseases.

Dr. Mello received his BS degree in Biochemistry from Brown University in 1982, and PhD from Harvard University in 1990. From 1990 to 1994, he conducted postdoctoral research at the Fred Hutchinson Cancer Research Center in Seattle, WA. Now Dr. Mello is an Investigator of the Howard Hughes Medical Institute, the Blais University Chair in Molecular Medicine and Co-director of the RNA Therapeutics Institute at the University of Massachusetts Medical School.

Besides the Nobel Prize, Dr. Mello’s work was recognized with numerous awards and honors, including the National Academy of Sciences Molecular Biology Award (2003), the Wiley Prize in Biomedical Sciences from Rockefeller University (2003), Brandeis University’s Lewis S. Rosnstiel Award for Distinguished Work in Medical Research (2005), the Gairdner Foundation International Award (2005), the Massry Prize (2005), the Paul Ehrlich and Ludwig Darmstaedter Award (2006), the Dr. Paul Janssen Award for Biomedical Research (2006), the Hope Funds Award of Excellence in Basic Research (2008). He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society.
