When World War II broke out, like several of his fellow male students, Shulman joined to defend his country.
In 1947, after his military discharge and without passing high-school equivalency exams, Shulman matriculated to the Leningrad Polytechnical Institute, where he was taught by the physicist Abram Ioffe.
In 1957, Shulman returned to his native Belarus, where he was employed by the Institute of Power Engineering of the BSSR Academy of Sciences.
In it, the authors generalized their own theoretical developments and descriptions of convective processes of heat and momentum transfer in external flow of nonlinear-viscous fluids past bodies of various geometry.
During the same years, Puris and Shulman discovered rubber mechanical behavior of gases in high-intensity rotating flows with considerable rates of shear deformations in the interdisk gap with eccentricity.
In the years before his death, Shulman worked a lot and achieved success in the field of biomedical problems and, in particular, the rheology of blood.
