Yazar Notları

Emeritus Professor A.Kaufman has 28 years' experience of teaching at the geophysical department in Colorado School of Mines He received his PhD. in Institute of Physics of the Earth (Moscow) and degree of Doctor of Science from the Russian Academy of Science . From 1981 to 20015 he published 14 monographs by Academic Press and Elsevier, describing different geophysical methods. Most of them are translated and published in Russia and China. He also holds three patents, which found application in the surface and borehole geophysics. A. Kaufman is a honorary member of SEG.
