## Biography and academic career

Gvishiani was born on October 29, 1948, in Moscow in the family of a prominent philosopher, expert in control theory and systems analysis, full member (academician) of the USSR Academy of Sciences, Dzhermen Gvishiani. Through Dzhermen he is the grandson of Mikhail Gvishiani, the NKVD general. On his mother's side Gvishiani is a grandson of Alexei Kosygin, Chairman of the USSR Council of Ministers in 1964–1980.
After graduating from Lomonosov Moscow State University (MSU), А. Gvishiani entered for postgraduate education at the chair of the theory of functions and functional analysis, Department of mathematics and mechanics of MSU. He was a student of an internationally famous mathematician Prof. Izrael M. Gelfand.
During Gvishiani's postgraduate studies he published a number of papers in leading mathematical journals. His main result was the proof of the Gelfand-Graev-Gvishiani formula for the characters of discrete series representations for the group of matrices with elements from a local non-Archimedean field (1973–74). During his university studies he was influenced by prominent Soviet scientists – I. Gelfand, М. Keldysh, V. Chelomey, V. Sadovnichy and V. Maslov (presently academicians), M. Graev, А. Kirillov.
In 1974 Gvishiani defended his PhD thesis devoted to the theory of functions and functional analysis. From 1974 to 1978 Gvishiani worked as assistant and then as associate professor at the Department of mathematics and mechanics of MSU.
In 1978 Gvishiani took a research position in the Schmidt Institute of Physics of the Earth of the Academy of Sciences. His career in this Institute developed from a research assistant starting as a research assistant up to deputy director general.
In 1983, Gvishiani defended his doctoral thesis in geophysics at the Schmidt Institute of Physics of the Earth.
In 1991–2005 Gvishiani established and headed the Center for geophysical data studies and network technologies of IPE RAS. During his work at the Center he created theoretical foundations of geoinformatics as a part of mathematical geophysics. In 2005 he was elected the director of the Geophysical Center of the Russian Academy of Sciences (GC RAS) and remained in that position till 2018. In 2018 by the decree of the Bureau of the RAS Earth Sciences Division he was appointed the chief scientist of GC RAS.
In 2006 he was elected a corresponding member of the Russian Academy of Sciences in geoinformatics, and in 2011 – a full member of Russian Academy of Sciences in geology and geo-informatics. Since 2007 he is a member of the bureau, and since 2008 Deputy Academician Secretary of the Earth Sciences Division of RAS. He is also a member of the RAS Scientific Council on the complex problems of Eurasian economic integration, modernization, competitiveness and sustainable development and Fellow of the Russian Geographical Society.
