[1] She then conducted her PhD research under Nicole Marthe Le Douarin at the Institut d'Embryologie cellulaire et moléculaire (Institute of Cellular and Molecular Embryology) in Nogent-sur-Marne,[1] which was affiliated to both Collège de France and the French National Centre for Scientific Research,[13] and defended her PhD thesis at the Pierre and Marie Curie University in Paris in 1991.

[1] After her PhD, in 1993, Dulac went to Columbia University as a postdoctoral fellow in Richard Axel's group.

[17][18] She is also currently a member of the Harvard Brain Science Initiative, as well as the Center for Brain Science and the affiliated Hock E. Tan and K. Lisa Yang Center for Autism Research at Harvard.

[19] Dulac's research spans from olfactory signalling in mammals through pheromones to the neuroscience of sex differences and parental behaviors.

[20] In 1995, working on mice, Dulac became the first to identify genes in mammals that encodes receptors for pheromones.
