My research deals with the inverse problem of seismic ray theory rooted in the theory of elasticity, and consisting of obtaining parameters characterizing the subsurface using seismological measurements. In the context of seismic ray theory, the measurements are traveltimes and polarizations of the seismic signal. A convenient experimental setup for such observations is provided by vertical seismic profiles with receivers located in the wellbores and the sources located on the surface, or with both sources and receivers located in the neighbouring wellbores.

我的研究涉及的地震射线理论的反问题，植根于弹性理论，并包括获得参数表征地下地震测量。在地震射线理论的上下文中，测量是地震信号的走时和偏振。用于这种观测的方便的实验设置由垂直地震剖面提供，其中接收器位于井眼中并且源位于地面上，或者源和接收器都位于相邻的井眼中。
