3-D shear wave radially and azimuthally anisotropic velocity model of the North American upper mantle (2011, methodology): “D shear velocity model (Lekic & Romanowicz 2010), developed using the Coupled Spectral Element Method (Capdeville et al. 2002).”
Multiscale full waveform inversion (2013, unknown): “While the computation of approximate sensitivity kernels via normal-mode summation or ray theory can be justiﬁed for mildly heterogeneous models (Leki´c & Romanowicz 2011; Zhou et al. 2011; Mercerat & Nolet 2012), the strong variations especially in the Anatolian part of the model (see Fig.”
A Computational Framework for Infinite-Dimensional Bayesian Inverse Problems Part I: The Linearized Case, with Application to Global Seismic Inversion (2013, unknown): “Already, successful deterministic inversions have been carried out at regional scales; for example, see [20, 21, 34, 43, 48].”
Seismic imaging: From classical to adjoint tomography (2012, methodology): “Any successive iteration which requires recomputing the Hmatrix under the updated model will be infeasible or computationally expensive, and hence is less often attempted in classical tomography (e.g., Bijwaard and Spakman, 2000; Lekić and Romanowicz, 2011).”

An anisotropic shear velocity model of the Earth's mantle using normal modes, body waves, surface waves and long-period waveforms (2014, background): “Adjoint techniques in tomography have been implemented at local (Tape et al. 2009) and regional scales (Fichtner et al. 2009; Zhu et al. 2012), while computational costs have impeded their application at global scales (e.g. Lekić & Romanowicz 2011).”
