Charles-Michel Marle (born 26 November 1934 in Guelma, Algeria) is a French engineer and mathematician, currently a Professor Emeritus at Pierre and Marie Curie University.
Returning to the École des mines in October 1958, his last year of study was interrupted in 1959 by the decision of the Minister of Industry, to send all junior civil servants of category A to Algeria to participate in the Constantine Plan.
He was then attached to the short-lived Common organisation of the Saharan regions [fr] and worked in Algiers, the Sahara and Paris on various industrial projects.
Between 1959 and 1969 he was seconded by the Corps des Mines to the French Institute of Petroleum (IFP), where he was research engineer, head of department and director of division.
While working at the French Institute of Petroleum, Marle's research focused on fluid flows in porous media, which are being investigated for applications in hydrocarbon field development.
