Some Important Contributions:Fundamental work in the theory of flow through porous materials. Developed a general method of solving twodimensional problems for seepage in homogeneous topsoils. "Kochina's research activity is characterized by a deep and wellorganized link with practice, a subtle attention to the physical essence of the phenomena being considered, an exact mathematical formulation of the relevant physical problems, and by a brilliant mastery of the mathematical apparatus."  P.S. Aleksandrov [1FF N20] Some Important Publications:Theory of Groundwater Movement, Translated by J.M. DeWiest, Princeton University Press (1962) [completed in 1952]

191921 Staff, Main Physical (later Geophysical) Observatory, Petrograd Education:Degree in Pure Mathematics, Petrograd University 1921Doctor of Physical and Mathematical Sciences 1940 References consulted:[28D WOM], [29 WWWS], [50 JT], [62 IT], [as1989rc], [Kochina's Memoirs, Nauka, gody Iyndi(in Russian)] , [1FF N20] Additional Information/Comments:The Russian Revolution of 1917 ended the system of gender discrimination against women that had existed in Tsarist Russia. Kochina benefited from this change as her courses at the Bestudzevskii women's program were then incorporated into the University of Petrograd.
Kochina is married to Nikolai Evgrafovich Kochin and they have two daughters.
