Biochemist Jennifer Doudna, a professor at UC Berkeley and faculty scientist in the Molecular Biophysics and Integrated Bioimaging Division, has been awarded the 2020 Nobel Prize in Chemistry for “the development of a method for genome editing.” She shares the Nobel Prize with co-discoverer Emmanuelle Charpentier, who currently serves as the scientific and managing director of the Max Planck Unit for the Science of Pathogens in Berlin. In 2012, Doudna and Charpentier’s research team detailed the underlying mechanisms of the CRISPR-Cas9 system – a component of the bacterial immune system that defends against invading viruses – and explained how it can be programmed to cut DNA at a target sequence.
