I am currently a Senior Manager at Maxar Technologies (formerly DigitalGlobe) in their Product R&D group, which does research toward next generation products in high-resolution satellite imaging. I have worked on a wide variety of projects including image analysis, machine learning, data science, large-scale inverse problems in bathymetry and atmospheric compensation, and parallel computations for large geodetic networks.
