He graduated from Tbilisi State University in 1940. In 1948 he left for Moscow where he worked at the V. Steklov Institute of Mathematics of the Academy of Sciences of the USSR till 1959. In 1959-71 A. Bitsadze was employed at the Institute of Mathematics of the Siberian branch of the USSR Academy of Sciences and the University of Novosibirsk. In 1971-78 he headed the Department of differential equations at the V. Steklov Institute of Mathematics as well as the Chair of Moscow Institute of Engineering and Physics. In 1978-83 A. Bitsadze served as the Research Supervisor and Director of the Institute of Applied Mathematics named after I. Vekua; from 1984 he was the professor of Moscow State University.

A. Bitsadze’s key works have to do with the mathematical theory of elasticity, theory of elliptic equations and systems, theory of the equations of mixed types, theory of hyperbolic systems, theory of non-local marginal problems, etc. The mathematical scientific circles are well-aware of ‘Bitsadze equation’, ‘Bitsadze-Samarski problem’, etc.

Andria Bitsadze died in Moscow. He was buried at the Donskoy Monastery.
