Kochin moved Moscow University in 1934 and worked there for the rest of his life. In addition he was head of the mechanics section of the Mechanics Institute of the Academy from 1939 to 1944.
Kochin's research was on meteorology, gas dynamics and shock waves in compressible fluids. He gave the solution to the problem of small amplitude waves on the surface of an uncompressed liquid in Towards a Theory of Cauchy-Poisson Waves in 1935.
He also worked on the pitch and roll of ships. In aerodynamics he introduced formulas for aerodynamic force and for the distribution of pressure.
He wrote textbooks on hydromechanics and vector analysis.
