Blanchard at the laboratory of parasitology in the Medical School of Paris ; appointed as head of works at the National Agricultural School in Montpellier, where he conducted research on parasitology in vertebrates and on bacterial infections in insects.
1914 Joined Ch. Nicolle at the Pasteur Institute in Tunis, succeeding the late A. Conor. Together with Cuénod and E. Conseil, commenced research on Mediterranean diseases and contributed to the discovery of the mode of typhus transmission to humans.
1914-1918 During First World War, served as a volunteer on the Serbian war front in 1915.
1919 By returning to Tunisia, he was put in charge of the laboratory for military bacteriology ; then returned to the Pasteur Institute in Tunis where he conducted research on mycetoma caused by spirochetes transmitted by rats in Tunis.
1920-1932 At the request of E. Roux, appointed as deputy director then director of the Pasteur Institute in Athens ; conducted research on smallpox, herpes and dengue virus ; devoted himself in the understanding of the role of intermediate hosts such as ticks and mosquitos in the transmission of the diseases ; moreover, conducted research on visceral leishmaniasis (kala-azar), cutaneous anthrax and leprosy.
1922 Organized a parasitological mission to Crete, on behalf of the Hellenic Pasteur Institute ; M. Langeron participated in it.
1924 Became a corresponding member of the French Society of Biology ( Société de biologie ).
1927 Elected associated member of the French Society of Exotic Pathology (Société de Pathologie Exotique, SPE).

1932-1962 At the request of E. Roux, appointed as director of the Pasteur Institute in Casablanca (Morocco) ; conducted research on typhus in mice, which led to the development of the first living vaccine against classical typhus fever, based on a bile-attenuated murine virus ; with M. Baltazard , intended to improve the making and preservation processes for the vaccine, by isolating the vaccinal virus from flea waste.
1935 Resumed studies on animal smallpox that he had commenced in Greece ; developped a vaccine against sheep pox.

1938-1939 Planned a large-scale vaccination campaign against exanthematic typhus in Morocco.
1940 While a minor plague endemic was recorded in the area of Marrakesh, conducted a comprehensive study on the ways of bubonic plague transmission, with M. Baltazard : the endemic form of the human disease appeared to be correlated with the presence of rats and specific skin parasites (infected rat fleas) ; another route of plague transmission was person-to-person contact through infected parasites, which led to human plague epidemic ; recommended preventive measures to fight the human plague.
1947 Was to be made a Commander of the Legion of Honour ; traveled to the Caspian provinces for studying malaria.
1951 (from Oct. to Dec.) Lectured on "vaccination against childhood contagious diseases" within the course organized by The International Center for Childhood, in Paris.
1953 Undertook epidemiological and ecological investigations into two tree populations in the countryside around Casablanca, composed of many small mammals and reptiles with specific parasites ; organized a poliomyelitis vaccination campaign of several thousands children, using a vaccine that he had developped with L.A. Martin, in order to mitigate an emerging epidemic detected in the Medina district, Casablanca.
