Catherine Dulac (born 1963) is a French-American biologist notable for research on the molecular biology of olfactory signaling in mammals, particularly including pheromones.She developed a novel screening strategy based on screening cDNA libraries from single neurons and a new method of cloning genes from single neurons. As a postdoc, Dulac discovered the first family of mammalian pheromone receptors with Nobel laureate Richard Axel.
