Alexander F. Goncharov's research concentrates on analyzing materials under extreme conditions such as high pressure and temperature using optical spectroscopy and other techniques. He received a Ph.D in physics from the Russian Academy of Sciences, Institute of Spectroscopy in 1983, and a combined MA and MSc in physics from the Moscow Institute for Physics and Technology in 1979.
Alex began his career at the Institute of Crystallography, Russian Academy of Sciences to become a world-recognized expert in optical spectroscopy under high pressure. In 2006 he left his post as a staff scientist at the Lawrence Livermore National Laboratory (LLNL) to rejoin Carnegie. He came to Carnegie initially as a Fellow during 1993 to 2002 period, became a Senior Research Associate and as a Research Scientist in 2005.
In 1991 his work won Annual European High Pressure Research Group Award for young scientists, and he was awarded by a prestigious Humboldt fellowship in Germany (MPI Stuttgart). At the LLNL we received the Associate Director (CMS) Award, 2005. At the Geophysical Laboratory today he continues leading the field of optical spectroscopy under extreme conditions of high pressure and temperature.
