Jennifer A. Doudna, Ph.D., Professor of Molecular and Cell Biology and Chemistry at the University of California, Berkeley, has devoted her scientific career to revealing the secret life of RNA. Using structural biology and biochemistry, Doudna's work deciphering the molecular structure of RNA enzymes (ribozymes) and other functional RNAs has shown how these seemingly simple molecules can carry out the complex functions of proteins.

Doudna is a pioneer of the revolutionary CRISPR/Cas9 gene-editing technology. Working with microbiologist Emmanuelle Charpentier, postdoctoral researcher Martin Jinek and graduate student Krysztof Chylinski, the team published their findings in Science in August 2012. Their paper immediately and dramatically transformed the field of molecular biology and genetics. Since then, Doudna and other scientists have shown that the CRISPR/Cas9 technique works in human cells, a finding with enormous implications for preventing and treating many intractable diseases, including viral illnesses, such as HIV, and genetic conditions, such as Down syndrome and sickle cell anemia.
