I am interested in theoretical and computational aspects of seismology. Seismology is a data-rich science with tremendous opportunities for understanding source processes and Earth structure. To pursue this I perform forward modeling of wave propagation through a media representative of Earth structure. The misfit between the synthetic thus generated and the observed data is then minimized using different approaches. The inversion technique and the applied minimization depends on many factors, such as theory underneath, linear or non-linear problem, dimensionality of the problem, and computational resources available. The uncertainty in the solution is also an integral part. For source inversion I have tried to quantify the uncertainty using Bayesian approach. These earthquake sources are the priori for the tomographic inversion. With the recent advances in high performance computing people have been able to carry out adjoint tomography at both regional and global scale. Similar effort is undergoing by us to better understand Alaska structure.
