Polina Landa

Polina Solomonovna Landa (; February 15, 1931 – September 21, 2022) was a Soviet physicist.

Early life and education Landa was born in Kyiv, the daughter of Solomon V. Landa. Her family was Jewish. She graduated from high school in Moscow in 1948. She earned a master's degree in physics from Moscow State University in 1953, and completed her doctoral studies there in 1960; her dissertation research, "On the stability of self-oscillatory systems and automatic control systems in the presence of random influences", was written under advisor Sergei Pavlovich Strelkov. She defended a second dissertation, "Investigation of the dynamic and statistical characteristics of optical quantum generators and amplifiers", in 1972.

Career Landa joined the faculty of Moscow State University in 1956, and remained there as a researcher and professor until she retired in 2020. She taught, did research on oscillations, with applications in plasma, lasers, and acoustics, and supervised twelve doctoral students through to the completion of their degrees. She was a member of the Russian National Committee on Theoretical and Applied Mechanics. Soviet Journal of Quantum Electronics, Chaos, Solitons, and Fractals, Physical Review E, International Journal of Bifurcation and Chaos, Biological Cybernetics, and Physics Reports. She contributed four articles to The Encyclopedia of Nonlinear Science (2006).
