Sergey lived there all his life on and was very much fond of that nice place.
From 1970 to 1989 he headed a Laboratory at the same institute, and from 1996
to 2005 he was director of the Institute of Geophysics as part of IGiG. Professor
S. Goldin was among world noted mathematical geophysicists.His major scientific
contribution was in the field of inverse kinematic problems of reflection and
refraction seismology. His original method of discontinuities became one basic
approach in the seismic migration theory which allowed quantitative comparison
of different subsurface imaging tools and synthesizing algorithms with prespecified
properties.
He
contributed a lot to the theory of optimal digital filters, statistical processing
of geophysical data, seismic tomography, and wave propagation in complexly structured,
heterogeneous, and anisotropic
media. Together with his students and colleagues,
he developed a new approach to seismic fields in the vicinity of singularities
(caustics) and led experimental and theoretical studies of nonlinear effects
associated
with wave propagation in complex and fluid-saturated media.
Through
recent years Sergey Goldin headed seismologic research in Siberia and explored
the problems of geophysics that were new for him.He studied earthquake physics
and seismic hazard issues and suggested a new strategy of geophysical and geodynamic
monitoring which moved the
emphasis from looking for earthquake precursors
toward looking into rock mechanics and physics of processes in the crust. The
new approaches he developed were concerned with theory and experiments on slow
movements and mechanisms of energy transfer in structured media, including faulted
lithosphere, role of external geodynamic forcing and its changes with time, dilatancy
effects. Sergey Goldin brought together geophysicists, mathematicians, physicists,
and geologists from many academic institutions of Siberia and all Russia to involve
them into several large integration projects for those problems. He initiated
and organized a yearly workshop on geophysics and rock mechanics which became
popular with many scientists and reported in special issues of the Russian journal
of physical mesomechanics /Fizicheskaya mezomehanika.
Sergey Goldin is
the author of five books and over two hundred papers in mathematical geophysics
and seismology. His /Seismic Traveltime Inversion/ that came out in the U.S. in
1986 opened the /Investigations in Geophysics /Series published by AGU. Professor
Sergey Goldin was a keen teacher. For eighteen years he taught and headed a chair
at Novosibirsk University, one of best Russian universities. He was also invited
lecturer at many universities worldwide: Stanford University and University of
Washington in the U.S., University of British Columbia in Canada, Technical University
of Trondheim in Norway, State University of Bahia in Brasil, University of Tonji
and Donjin Oil University in China. The
professional activities of S. Goldin were overwhelming and spanned research, teaching,
editorial, and consulting duties. He was Full Member of the Russian Academy of
Sciences, Member of European Academy of Sciences and of American Geophysical Union,
and vice-president of the
Asian Seismologic Commission since 2004. In recognition
of his scientific success he was awarded several medals, orders, and prizes, namely
State Award of Russian Federation (highest Russian award), State Prize of the
Russian Federation, Schmidt Prize (together with N.N.Puzyrev) for the theory of
kinematic interpretation of seismic waves, Fedynsky medal for outstanding contribution
to national geophysics, and others. Beyond
science, Sergey was a gifted poet and author of two books of poems, played the
mandolin, went into sports. After all, he was a very nice person, joyful and encouraging.
He was somebody who makes people feel at home, very easy to get along with, and
always surrounded with pleasant atmosphere. He loved life, loved his science and
people around him. And his friends, colleagues, and students, returned him the
warmest affection. All
people who met Sergey Goldin will keep memory of a remarkable personality, an
excellent and respectable scientist, a talented and loved teacher. He
passed away on 18 May 2007 at an age of 71, in his full activity, having justify
many unfinished projects to be taken up by his students and colleagues.
