Training across biological disciplines
Born in Paris, Monod obtained a science degree in 1931 and his doctorate in 1941. His training brought together genetics, quantitative biology and biochemistry, including research at the California Institute of Technology in 1936. After the liberation of France, he joined Lwoff’s department at the Pasteur Institute.

Enzyme induction and the operon
Monod investigated how microorganisms produced particular enzymes in response to environmental conditions. In the late 1950s his collaboration with Jacob connected enzyme induction with regulatory genes. Their operon model explained coordinated control of genes involved in related functions, providing an experimental and theoretical framework for gene regulation.
Research and leadership at Pasteur
Monod became head of cellular biochemistry at the Pasteur Institute in 1954 and its director in 1971. He also held teaching positions at the Sorbonne and the Collège de France. He shared the 1965 Nobel Prize in Physiology or Medicine with Lwoff and Jacob.
