Research Area: Large-scale sparse optimization, compressive sensing, primary estimation (EPSI), simultaneous source separation

About me: I've been with SLIM since 2006, first as an undergraduate student and eventually stayed with the lab throughout my graduate career. During my time here I've worked on many topics related to application of sparse optimization and compressive sensing. Previous works include compressive one-way wavefield propagation, separation of simultaneously acquired data into single-source pre-stack gathers, and large-scale parallelization of the SPGL1 optimization algorithm. Currently focusing on the application of recent sparse optimization techniques to the Estimation of Primaries by Sparse Inversion (EPSI) problem.
