Emmanuelle Marie Charpentier (French: [ɛmanɥɛl ʃaʁpɑ̃tje]; born 11 December 1968) is a French professor and researcher in microbiology, genetics, and biochemistry. As of 2015, she has been a director at the Max Planck Institute for Infection Biology in Berlin. In 2018, she founded an independent research institute, the Max Planck Unit for the Science of Pathogens. In 2020, Charpentier and American biochemist Jennifer Doudna of the University of California, Berkeley, were awarded the Nobel Prize in Chemistry “for the development of a method for genome editing” (through CRISPR). This was the first science Nobel Prize ever won by two women only.

Charpentier is best known for her Nobel-winning work of deciphering the molecular mechanisms of a bacterial immune system, called CRISPR/Cas9, and repurposing it into a tool for genome editing. In particular, she uncovered a novel mechanism for the maturation of a non-coding RNA which is pivotal in the function of CRISPR/Cas9. Specifically, Charpentier demonstrated that a small RNA called tracrRNA is essential for the maturation of crRNA.
