He continued his studies at the University of Riga , where he became active in socialist politics, including giving political speeches and working for an underground newspaper. Bers received his Ph. Having applied for postdoctoral studies in Paris, he was given a visa to go to France soon after the Munich Agreement , in which Nazi Germany annexed Czechoslovakia. He and his wife Mary had a daughter in Paris. They were unable to obtain a visa there to emigrate to the US, as the Latvian quota had filled, so they escaped to the south of France ten days before the fall of Paris, and eventually obtained an emergency US visa in Marseilles, one of a group of 10, visas set aside for political refugees by Eleanor Roosevelt.
The Bers family rejoined Bers' mother, who had by then moved to New York City and become a psychoanalyst, married to thespian Beno Tumarin. After the war, Bers found an assistant professorship at Syracuse University — , before moving to New York University — and then Columbia University — , where he became the Davies Professor of Mathematics,   and where he chaired the mathematics department from to National Committee on Mathematics from to , and chaired the Mathematics Section of the National Academy of Sciences from to Late in his life, Bers suffered from Parkinson's disease and strokes.
He died on October 29, Bers' doctoral work was on the subject of potential theory.

While in Paris, he worked on Green's function and on integral representations. At Brown, he began working on problems of fluid dynamics , and in particular on the two-dimensional subsonic flows associated with cross-sections of airfoils. At this time, he began his work with Abe Gelbart on what would eventually develop into the theory of pseudoanalytic functions.
Through the s and s he continued to develop this theory, and to use it to study the planar elliptic partial differential equations associated with subsonic flows. Another of his major results in this time concerned the singularities of the partial differential equations defining minimal surfaces. In an interview following his resignation, Logokwa affirms that the Sudanese government has set up camps to train "terrorists.
The military commander of Kadogle, the principal town in southern Kordofan, claims that government forces have destroyed 13 rebel bases in the area, and that more than 32, civilians have left SPLA-controlled regions.
