    Abstract
    The objective of this thesis is to investigate new methods in reflection seismology for estimating subsurface velocity models accurately and efficiently. Full waveform inversion (FWI) is a state-of-the-art approach that can yield high-resolution models. However, multiple problems, including high computational cost, spurious local minima and possible geologically-implausible solutions, have prevented widespread applications of FWI for reflection data. These problems correspond to the fact that we in practice must estimate numerous model parameters with inadequate data (e.g., limited aperture, ...
