RNDr. Ivan P\u0161en\u010d\u00edk<\/strong>, CSc (1946) has been a researcher at the Institute of Geophysics, former Geophysical Institute since 1970. His subject is the study of seismic wave propagation in complex, layered, elastic or absorbing, isotropic and anisotropic, inhomogeneous media. For the study of forward and partially also inverse problems he uses high-frequency asymptotic methods, such as the ray method or the method ofsummation of Gaussian beams.<\/p>\n

He graduated from Charles University, Prague, in physics (1963-1968). He obtained the degree CSc (an equivalent to PhD) from Czechosl. Acad. Sci., Prague, in geophysics in 1974. He stayed at various seismological institutions abroad, for example, in Brazil, Canada, China, France, Germany, Japan, Sweden, USA, USSR.<\/p>\n
