In 1948 he attended the international congress of Mechanics in london, where, thanks to sydney goldstein, he had the opportunity to meet a large number of talented colleagues and was invited to spend some time in the department of applied Mathematics of the University of Manchester, headed in 1949 by goldstein and in 1951 by his long-lasting friend James lighthill. His thesis on the subject of conical supersonic flows was published by ONERA (The French Aerospace Lab)

Paul germain noted in his memoirs that his progress in understanding fluid mechanics was then mostly due to his close relations with and good knowledge of the works of Paco lagerstrom, saul Kaplun, and Julian Cole, his colleagues during his stay at the california institute of Technology, and later to the academic year spent by Paco in his laboratory, and also to the two visits in Paris of Milton Van dyke for one full year each. all of them theorized on asymptotic singular expansions, which germain came to use frequently.

He obtained many important new results in the mathematical theory of partial differential equations of mixed types, with the aim of finding a better understanding of the aerodynamical properties of transonic flows. One must also mention his significant contributions to the theory of shocks with Jean Pierre guiraud, with whom he gave the complete theory of the shock structure -- to any order -- a question previously studied by russian and american scientists but erroneously after the second order.

in 2006 he published Memoirs of a Christian Scientist, a work that enlightens the route and life of an outstanding figure. A final story about Paul Germain: he was quite perturbed during the academic year 1953–1954 by the statement of a young boy who filled the tank of his car at a gas station near Brown University who told him one day, "Let me be straightforward.
