I am an applied mathematician with expertise in several areas including large-scale numerical modeling, high-performance computing, fast solvers, inverse problems, computational geophysics, and biomedical imaging.
I have got my Ph.D. from the University of Houston, focused on preconditioned iterative solvers for anisotropic problems. I am currently a senior research scientist at Skoltech working on data-driven methods for forward and inverse geophysical modelling.
I am also the author and lecturer of the original course Advanced Solvers for Numerical PDEs.
Data-driven methods for geophysics and geoscience.
Computational methods for PDEs: flow in porous media, diffusion/potential problems, electromagnetics, elasticity,
Development of fast forward and inverse modelling algorithms.
