About
Alexander S. Lipatov born in Moscow, Russia. He obtained his
Engineer-Physicist in Aerodynamics and Thermodynamics (MS, 1969) and Candidate of Sciences degree in Plasma Physics (PhD, 1972) from Faculty of Aerophysics and Applied Mathematics, Moscow Institute of Physics and Technology (State University).
In 1988 he obtained his Doctor of Sciences degree in Theoretical and Mathematical Physics from Space Research Institute USSR/Russian Academy of Sciences (IKI RAS). In 1995 he has been awarded the scientific title “Professor of Space Physics” from the Russian State Committee for Higher Education. He worked in IKI for more than 24 years, starting as research scientist and finishing as Professor/Lead Scientist. He also worked for more than 23 year as Professor at the Faculty of Problems of Physics and Power Engineering, Moscow Institute of Physics and Technology (State University). During 1990-1993 he fulfilled duties of Deputy Head at the Affiliated Chair (Department) “Space Physics” at the above University. The Chair is based at IKI RAS and at that time involved two specializations: “Space Physics” and “Computational Physics”.
His research in collaboration with academicians, Profs. D.Sci.’s R.Z. Sagdeev,
A.A. Galeev, and L.M. Zelenyi included a global hybrid–drift-kinetic–multifluid multiscale modeling of the interaction of the solar wind with magnetosphere of the Earth, Moon,
Venus, comets and extra-solar planets. He had also performed a hybrid/fully kinetic simulation of wave-particle interactions at the front of collisionless shocks and in the plasma systems with reversed magnetic field configuration.
Since 1992 he occupied long term visiting Professor positions in the USA, Germany and Canada.
He worked more than 17 years as a Senior Scientist at GPHI/GEST UMBC (673) in a collaboration with Drs. E.C. Sittler, J.F. Cooper, R.E. Hartle, M. Sarantos, B. Giles, D. Gershman, and L. Avanov, and his duty was a 3D hybrid-kinetic simulation of the plasma environment near Titan, Europa, Moon, the Solar Probe Plus, and Magnetospheric Multiscale mission.
Research interests
My basic research interests concern numerical simulation
in astrophysical and laboratory plasmas:
(a) Global multidimensional multiscale hybrid (fluid-kinetic)
simulation of the interaction of the solar wind
with the magnetosphere of the planets - the Earth, moons,
Venus, Mars, comets, etc.
(b) Hybrid/kinetic multiscale simulation of turbulent processes, particle heating and acceleration at the front of
collisionless shocks and magnetic field reconnection in the plasma systems with reversed magnetic field
configuration with application to solar flares, magnetosphere of the planets, bow shocks, interplanetary shocks and the termination shock.
(c) Hybrid simulation of the (plasma and dust) beam propagation in space plasma.
(d) Boltzmann simulation of the interaction of atoms
from the local interstellar medium with the heliosphere (including charge exchange and photoionization processes).
(e) Kinetic modeling of the background plasma-spacecraft interaction.
(g) Multiple blast waves from distributed charges in geo-space plasmas.
Teaching interests
For more than 20 years Prof. D.Sc. A.S. Lipatov worked
in Moscow Institute of Physics and Technology (State University) at the Chair "Space Physics" which is located in Space Research Institute USSR/Russian Academy of Sciences (IKI RAS). In particular, he taught the following courses for
undergraduate and graduate students:
"Numerical Methods for Space Research" (1973 - 1979),
"Introduction to Computational Physics" (1980 - 1993),
"Numerical Methods for Space and Plasma Physics (1994-1996). These courses (I-III) (64 academic hours) included an introduction to the theory of numerical schemes,
numerical methods in magnetohydrodynamics, numerical methods in plasma physics and applications of these methods to the investigation of MHD and kinetic processes in space plasma systems: planetary magnetospheres, nonmagnetic planets and comets, heating and acceleration of particle at
collisionless shocks, heating and acceleration of particle under
magnetic field reconnection in neutral current layers (magnetotails), and generation of waves by beam and pickup ions in an inhomogeneous background.
The seminars (32 academic hours) included the study of details of simulation processes and computer training (simulation of relatively simple problems). The problems were solved in the following steps: formulation of the physical
phenomenon, development of a mathematical model, discrete model, numerical algorithm, design of a computer experiment, and diagnostic of simulation results.
In both the Lectures and Seminars Prof. D.Sc. A.S. Lipatov has used recent publications from internationally recognized
journals: J. Geophysical Research,
Geophysical Research Letters, Space Sci. Review,
Planetary and Space Science, Physical Research Letters,

Administrative Duty
From the beginning of Jan. 1990 until August 1993 A.S. Lipatov occupied the position of Deputy Head of Basic Speciality (chair, subfaculty) "Space Physics" (including the "Space Physics" and "Computational Physics" basic
specialities). These duties included all kinds of problems associated with the activity of the Basic Chair: preparation of lecture and seminar schedules, allocation of teaching loads (lectures, seminars and graduated students) among
professors, attestation of scientific work to graduated students (each semester), selection of claimants (candidates) to student after exams, and the organization and conducting of the regular meetings of the members of the Chair. A.S. Lipatov participated (together with Head of Speciality - Director
IKI RAS, Prof. A.A. Galeev) in the development of a strategy for training specialists in Physics and Applied Mathematics in collaboration with Heads of other Specialities, Dean and Rector of the Moscow Institute of Physics and Technology.
