Biography:
He was born on July 3, 1953 in Ishim city of Tyumen Oblast of Russian SSR.
In 1975 he graduated from Novosibirsk State University. After graduating from M. V. Lomonosov Moscow State University in 1979-1990 he worked at the Crimean Astrophysical Observatory of the USSR Academy of Sciences as a scientist employee.
In 1984 and 1986 he was on an internship at the Copernicus Astronomical Science Center in Warsaw city.
Since 1990 to 1994 he worked at the Institute of Astronomy at Cambridge University (since 1994 to 2013 he worked at the Hansen Laboratory of Experimental Physics at Stanford University as a senior researcher). Since 2013, he has been a professor at the New Jersey Institute of Technology (NJ1T), serving as director of the Big Bear Solar Observatory since 2013 to 2014. Since 2015, he has been the director of the Center for Computational Heliophysics, which he organized for analysis. and modeling large arrays of data from modern telescopes.
In 1990 he received a doctorate in physical and mathematical sciences in astrophysics.
In 2013 he received the title of professor of physics.
During 2009-2012 he was the president of the commission №12 of the International Astronomical Union.
In 2014, he was elected an honorary member of the American Geophysical Union. He is also a member of a number of scientific councils and editorial boards of international and domestic journals.
The main scientific works of the scientist relate to the fields of astrophysics, solar physics, computational astrophysics, extraatmospheric and terrestrial astronomy. He is the author of more than 250 scientific papers.
In the 80's of the twentieth century together with Andreev A. S. in a one-dimensional nonstationary approximation taking into account the effects of saturation of heat flux and heating of the ionic component of plasma performed numerous simulations of energy release and transfer processes in high-temperature plasma (Ge~107K, ne~1010cm-3) during solar flares.
In the 1970s and 1980s in collaboration with B.C. Sokolov, Yu.P. Popov, M. A. Livshits and MM Katsov developed the theory of gas-dynamic and MHD processes in solar and stellar flares based on numerical simulation methods. His models of the interaction of a beam of accelerated electrons with the atmospheres of the Sun and dwarf stars allowed us to establish the nature of the observed optical radiation and high-velocity plasma currents and to come closer to understanding the physical nature of flares. Since the 1980s, together with A. B. Severny, V. A. Kotov, T. T. Tsap, V. Dzhembovsky and D. Gaff worked on the creation of helioseismology - a new direction in solar physics, which provides the key to understanding the internal structure, evolution and magnetic activity of the Sun. For the development of unique methods for solving inverse problems of helioseismology in 2005 he was awarded the J. Wempe International Prize, awarded by the Leibniz Institute of Astrophysics (Germany). From 1994 to 2004, he worked on the Solar and Heliospheric Observatory Extraterrestrial Astronomy Project, leading a helioseismological group at Stanford University. He developed a new method of acoustic tomography, which allowed to obtain the first three-dimensional images of plasma structures and currents inside the Sun. Since 2004 he has been managing the scientific component of helioseismology and magnetism of NASA's Solar Dynamics Observatory (SDO). Under his leadership, the fundamental problems of solar physics in measuring the internal dynamics and meridional circulation of the Sun, which are of paramount importance for the theory of solar cycles, were solved.
Participates in NASA's "Kepler", "IRIS", "SDO" space programs and the largest solar telescope program. He successfully works with young scientists, together with the NASA Science Center is the organizer of summer programs for young astronomers. Six candidate dissertations were completed and defended under his scientific supervision.
His work has won NASA awards.
In his honor asteroid of Main Belt #8339 , which discavered in 1985 by N. S. Chernikh, was named Kosovitia.
