Areas of research interests:
Seismic wave propagation, computational seismology and theoretical
geophysics, in particular theoretical development and accuracy
estimation of computational methods. The main attention is devoted
to the properties of wave fields in 3-D models at high-frequencies
and to asymptotic methods, especially to the computation of travel times,
paraxial ray approximations, summation of Gaussian beams and packets,
and to their applications in refraction and reflection seismics.
Summation of Gaussian beams and packets,
generalization of the Maslov asymptotic method using
the linear canonical transform,
coupling ray theory,
ray tracing and dynamic ray tracing
in 3-D heterogeneous anisotropic structures,
paraxial ray methods,
higher-order derivatives and perturbations of travel time,
chaotic behaviour of rays,
sensitivity of seismic waves to the structure,
stochastic inversion of travel times and of wave fields,
accuracy estimation of various approximate methods.
